Re: Hide Custom Page / Subarea / Group based on the Security Role for a Model Driven App?
Took me a second to digest this page, so I'm leaving this note for others who find their way here:
Just so the terminology is clear (based off the words used in the Power Apps Sitemap Designer) this functionality (view based on security role / privileges) exists for Subareas but not for Areas or Groups.
Area (light blue highlight) = grouping of Groups
Group (yellow highlight) = grouping of subareas
Subarea (green highlight) = dataverse table, custom page, dashboard, URL, Web resource

Hiding whole Areas and Groups would save a lot of duplicate work, especially when an Area contains dozens of Groups with several Subareas each. Will upvote the community request once it stops throwing errors when I try to do so.
