Use cases:

Create chat room with specific type, and add user. Channel layer should be created if user are online and all online users should to receive messages
Private chat room (chat between 2 members). Nobody can add new members.
Group chat (chat between multiple users). Users could be added through API endpoint call
moderation part is missed at the moment

Flow:
