DS Feedback endpoint implementation differs from Mentee/Mentor implementation

[gpwolfe]

The API implementation for Mentor and Mentee endpoints uses a URL that includes a unique ID (profile_id) when operating the Update endpoint. The Feedback endpoint does not, but perhaps should, match this implementation (as per conversation with @BrokenShell)

Screenshot shows the endpoints in question, with {profile_id} appended to URL for Mentor and Mentee endpoints, but not Feedback endpoint.
