The Access Tab, which is within the Team Card, shows all of the users who have access to the document. Only users who have been invited and have accepted their invitations to the Challenge Definition will be shown on the Access Tab.
User status, access rights, and permissions can be viewed and modified from the Access Tab by Owners, including a user's role and whether a user is able to invite others to the Challenge Definition. Users can also be removed by Owners in this tab. Additional users can be added from the Invitations Tab within the Team Card.
