Guest
Guests can chat, react, use their camera and mic, and move their own camera or screen share. They do not add, move, or play with the room's content. Someone inside can let them in after a knock.
Member
Members can decorate, add and use room content, invite friends as members, and answer knocks. They can make a guest a member. They normally enter without knocking unless the door is closed.
Admin
Admins can change room settings, lock content, close the door, and manage members and guests. They can turn off someone's camera or mic once; that person can turn it back on.
Owner
The owner created the room and can manage everything, including choosing admins, transferring ownership, and deleting the room. Only the owner manages the admin role.
