Web Portal 9.1 - Sub identities

New Angular web portal, One Identity version 9.1

I created a main identity and then I created a sub-identity linked to the main one. Viewing the overview on the new portal, I read "Personalized administrator identity" in the Identity form, but it is not possible to trace the identity to which it is linked.

In the old web portal, there was the HyperView which showed the binding graphically.

Any suggestion?
