      );
    }
    ```
  </Tab>

### Actions

[Actions](/ui-kit/react-native/v4/components-overview#actions) dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

##### 1. onItemPress

`onItemPress` is triggered when you click on a ListItem of the of the `CallParticipants` component. It does not have a default behavior. However, you can override its behavior using the following code snippet.

<Tabs>
  <Tab title="App.tsx">
    ```tsx theme={null}
    import { CometChat, CometChatCalls } from "@cometchat/chat-sdk-react-native";
    import { CometChatParticipants } from "@cometchat/chat-uikit-react-native";
    import {
      CallLog,
      CallLogRequestBuilder,
    } from "@cometchat/calls-sdk-react-native";

    function App(): React.JSX.Element {
      const [loggedInUser, setLoggedInUser] = useState<CometChat.User>();
      const [callLog, setCallLog] = useState<CallLog>();
      useEffect(() => {
        //code
        CometChatUIKit.login({ uid: "uid" })
          .then(async (user: CometChat.User) => {
            setLoggedInUser(user);
            const callLogRequest = new CallLogRequestBuilder()
              .setLimit(1)
              .setCallStatus("cancelled")
              .setAuthToken(user!.getAuthToken())
              .build();

            callLogRequest
              .fetchNext()
              .then((callLogs: CallLog[]) => {
                setCallLog(callLogs[0]);
              })
              .catch(() => {
                //handle error
              });
          })
          .catch((error: any) => {
            //handle error
          });
      }, []);

      const onItemPressHandler = (item: any) => {
        //code
      };

      return (
        <>
          {callLog && (
            <CometChatParticipants
              call={callLog}
              data={callLog!.getParticipants()}
              onItemPress={onItemPressHandler}
            ></CometChatParticipants>
          )}
        </>
      );
    }
    ```
  </Tab>
</Tabs>

##### 2. onBack

The `onBack` function is built to respond when you press the back button in the AppBar. The back button is only displayed when the prop `showBackButton` is set to true.

<Tabs>
  <Tab title="App.tsx">
    ```tsx theme={null}
    import { CometChat, CometChatCalls } from "@cometchat/chat-sdk-react-native";
    import { CometChatParticipants } from "@cometchat/chat-uikit-react-native";
    import {
      CallLog,
      CallLogRequestBuilder,
    } from "@cometchat/calls-sdk-react-native";

    function App(): React.JSX.Element {
      const [loggedInUser, setLoggedInUser] = useState<CometChat.User>();
      const [callLog, setCallLog] = useState<CallLog>();
      useEffect(() => {
        //code
        CometChatUIKit.login({ uid: "uid" })
          .then(async (user: CometChat.User) => {
            setLoggedInUser(user);
            const callLogRequest = new CallLogRequestBuilder()
              .setLimit(1)
              .setCallStatus("cancelled")
              .setAuthToken(user!.getAuthToken())
              .build();

            callLogRequest
              .fetchNext()
              .then((callLogs: CallLog[]) => {
                setCallLog(callLogs[0]);
              })
              .catch(() => {
                //handle error
              });
          })
          .catch((error: any) => {
            //handle error
          });
      }, []);

      const onBackHandler = () => {
        //code
      };

      return (
        <>
          {callLog && (
            <CometChatParticipants
              call={callLog}
              data={callLog!.getParticipants()}
              onBack={onBackHandler}
              showBackButton={true}
            ></CometChatParticipants>
          )}
        </>
      );
    }
    ```
  </Tab>

### Filters

**Filters** allow you to customize the data displayed in a list within a `Component`. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using `RequestBuilders` of Chat SDK.

The `CallParticipants` component does not have any exposed filters.

***

### Events

[Events](/ui-kit/react-native/v4/components-overview#events) are emitted by a `Component`. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The `CallParticipants` does not produce any events.

***

## Customization

To fit your app's design requirements, you have the ability to customize the appearance of the `CallParticipants` component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

### Style

Using **Style** you can **customize** the look and feel of the component in your app, These parameters typically control elements such as the **color**, **size**, **shape**, and **fonts** used within the component.

##### 1. CallLogParticipants Style

To customize the appearance, you can assign a `CallLogParticipantsStyle` object to the `CallParticipants` component.

### Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

Here is a code snippet demonstrating how you can customize the functionality of the `CallParticipants` component.
