Roles and permissions
Owners and admins manage a team. Members use it.
- Owners do everything admins can, and also change roles, set the team's permissions (Members See ROIP, Who Can Invite, Join Code On), hand the team over and delete it.
- Admins edit the team's profile, invite people, manage the join code and remove members.
- Members see their own sessions and the team's views.
Every team has exactly one owner.
