Group APIs

Tencent Cloud Chat SDK supports five preset group types, each of which pertains to different scenarios.

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: A user can join and leave a community freely. It is suitable for chat scenarios with a super large number of community members, such as knowledge sharing and game discussion. This feature is supported by a client with the SDK enhanced edition v5.8.1668 or later and the web SDK v2.17.0 or later. To use it, you need to purchase the Premium edition, and then enable it via console > Feature Configuration > Group configuration > Group feature configuration > Community.
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.
