The GUID is typically the primary ID of the group from your database. If you do not store group information in your database, you can generate a random string for use as GUID.
GUID can be alphanumeric with underscore and hyphen. Spaces, punctuation and other special characters are not allowed.
Once a participant joins a group, they become a member. Members remain part of the group indefinitely — to stop receiving messages, calls, and notifications, a member must be kicked, banned, or leave the group.
