No option to grant notification right

Hi,

our client eagerly wants the right to grant receiving notifications to all users, because every user should get noticed about duplicates he’s uploading.

But as I tried to explain in the following issue description, the option to grant is not shown in the admin backend.
https://github.com/pimcore/pimcore/issues/6979
I suppose some extension is overwriting or removing the checkbox, so that it is not shown. But that’s only an idea. In other projects, there is a checkbox to grant notifications to normal users.
Does anybody know this problem? Is it solved in a new pimcore version?

Many thanks in advance
