No option to grant notification right


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.
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
