    The members of a meeting group can join and leave freely, and can view the group’s message history upon entry. Meeting groups are ideal for TRTC scenarios such as audio/video conferences and online education.

    A community group can have up to 100,000 members. A member can join and leave freely, and message history is stored. A user can search for a community group by group ID and join it, without the need for approval by an admin.
