Team
Members and invitations.
Team lists the workspace's members with their role, and the invitations that are open.
An administrator invites a person by email with the role they should have — administrator, user or client; the invitation is accepted by signing in or registering with that address. A member's role can be changed and a member removed by an administrator.
A member with the client role sees nothing until attached to a client — Clients. What each role may do is in Roles and permissions.
