There are three types of users you can invite to Bïrch:
Admin has the same access as the owner does.
Users - Can use all Bïrch features and connected ad accounts, but cannot access integrations, team, or billing settings. Admins can assign them to specific workspaces, and they only see the workspaces they are assigned to.
