For instructors who manage a group or teach classes in it, we recommend adding them to the group with group administrator permission. With group administrator permission, instructors can handle operational tasks themselves, such as adding members, assigning subjects, reviewing learning analytics, and setting class hours, without going through an organization administrator.
Affiliation.Groups.Members.Administrator permission.Add / Update permission.Only users who already belong to the organization that the group belongs to can be added to the group. If the instructor does not yet belong to the organization, first add them to the organization by inviting members to the organization.
Also, if the group has no administrator yet, only an organization administrator can add the first group administrator. If you get an error when trying to work as a group administrator, ask an organization administrator for help.
