The table

Each operator with their role, status (active, invited or disabled) and when they joined. Admins change another operator’s role from the drop-down and Disable or Enable them. A disabled operator cannot sign in. An admin who got in through ADMIN_EMAILS sees a note that their operator row is created on first sign-in, after which other admins manage it here.

Inviting

Enter an email, optionally a name, and a role; Invite creates the operator as invited and sends the invitation email. They sign in to the back office with that address through the same sign-in provider as the client app, and become active on first sign-in. See Sign in and roles for what each role sees.
