Community: Community supports up to 100,000 members and a user can join and leave a community freely without approval. 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 edition V5.8 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.
