What task can a Group Admin who is not a System Admin perform?

A Group Admin has specific responsibilities and permissions that differ from those of a System Admin. One of the key capabilities of a Group Admin is the ability to manage the users within the group they own. This includes the authority to remove users from that group as needed. The ownership of the group grants the Group Admin the necessary permissions to manage its members effectively.

Other options describe actions that go beyond the authority of a Group Admin. For instance, assigning a user to the Group Admin role typically requires System Admin privileges, as this involves modifying user roles across the platform. Similarly, deleting a group that the Group Admin does not own is not permitted, as it falls outside of their ownership rights. Lastly, changing settings to allow external users to join is generally a governance feature that only a System Admin can modify, thereby ensuring strict control over membership and access within the organization.

Thus, the ability of a Group Admin to remove a user from a group that they own is a clear reflection of their role and responsibilities, aligning with their function in managing group membership effectively.
