An Approver is a person authorized by an AGPM Administrator (Full Control) to create, deploy, and delete Group Policy Objects (GPOs) and to approve or reject requests (typically from Editors) to create, deploy, or delete GPOs.
Make sure that you are connecting to the central archive for GPOs. For more information, see Configure an AGPM Server Connection.

Also, an Approver has full control over GPOs that he created or controlled.
