Agreed. Unless it's a really frequently used UI, my company defaults to showing all options to all users regardless of permissions. It's better to see "Manage users" in the settings menu which takes you to a page explaining that you don't have permission as opposed to seeing nothing and wondering why it's not there even though the help article says it should be there.

No, putting an explanation on the help article that this feature is only available to admins doesn't work. No one reads anything.

Thanks for putting this into words better then I would. I was screaming discoverablity at my screen.

Modern software UX is gaslight central. I think people are scared that if users read something they'll get confused or frustrated, so they just default to... nothing? Even error messages are dying. Half the time shit doesn't work and there's no indication. Maybe a loading spinner just disappears and that's supposed to be your clue to try again.
