I have added an Application overlay with an additional DecisionManager:Supervisor access group/role as per DSM Advanced course module exercise. But I don't see "Proposition Group Authorization" option in the dropdown on "Edit" hyperlink (Please see screenshot).
Can someone please assist on as how to enable that option..?
Based on your screenshot I believe you are working on Pega 7. The proposition authorization feature is not available in Pega 7. With the introduction of Decision data rule (from ML 8 or 9) to manage propositions we have removed the authorization model for propositions.
