By default, chat room members can only send and read messages. As needed, you can promote members to administrator, and they can perform the tasks listed in this section. Also, if you want to leave a chat room, and you're the only administrator, you must promote someone to administrator before you can leave.
To promote room members
In the sidebar, open the chat room.
Choose the ellipsis menu located to the right of the chat room name, then choose Manage members.
Locate the member that you want to promote, open the list in the Role column, and choose Administrator.
Choose Done.
