Once a participant has chosen their own feedback providers, it is not currently possible to give them access to update this list directly.
If the list of feedback providers is awaiting approval, the person being assessed can ask their approver to make the updates
If the list of feedback providers has already been approved, the person being assessed can ask a project administrator to make updates.
Asking the project administrator to make these changes helps to protect the anonymity of the feedback providers. The project administrator can — for example — see if someone has already provided feedback, and in this case might choose not to remove or replace them.
