Group APIs

Tencent Cloud Chat SDK supports five preset group types, each of which pertains to different scenarios.
Work group (Work): Users can join a work group only after being invited by members of the group. This group type is the same as private group (Private) in earlier versions.
Public group (Public): Users can join the group through requests, which need to be approved by the group owner or group admin.
Meeting group (Meeting): used together with TRTC to enable scenarios such as video conferencing and online education. Users can join and leave the group freely and view the message history before they join. Same as chat room (ChatRoom) in earlier versions.
Community (Community): A community allows users to join and leave freely and is ideal for ultra-large community group chat scenarios, such as knowledge sharing and game communication.
Audio-video group (AVChatRoom): An audio-video group allows users to join and leave freely and is suitable for scenarios such as live streaming and chat rooms with on-screen comments. There is no limit on the number of group members.
