On Azure I added a service principal X to my databricks workspace. I therefore had the Service Prinicpal Manager role on that service principal X. I accidentally downgraded my rights to Service Principal User and now can's get my Managers role back. I am an workspace admin and can delete the service principal entry X. If I add the just deleted service principal X again, I will only receive the Service Principal User role, not the Manager role.

If I create any new service prinicpal Y with a syntactically valid app-id I will receive the Service Principal Manager role for Y. 

This seems inconsistent, since I can delete it but not manage it. How can I reclaim my Service Managers role back?
