Permission for "Inherit permissions from higher levels"

One question: In Plone 5, by which permission is the option "Inherit permissions from higher levels" on the sharing tab protected ? Is it the permission "change local roles" as for the other checkboxes on the sharing tab, or is there a special one for this option ?

We want to make this option available depending on a role independant from the "change local roles" permission.

Thank you in advance.

It's the sort of question it's best to look at the code for I'm afraid @tdkuehnel

5sec look and I'd say it's possible. Seems that there is both a "Sharing page: Delegate roles" and a seperate role for each role you can delegate. So in theory giving just "Sharing page: Delegate roles" might work? but you'd have to either try it or look at the code more
