Test feedback when opening applications from the Applications menu

Originally created by @sajolida on #15738 (Redmine)

While working on #15101 (closed) we realized that the lack of feedback might also affect other applications and not only the desktop launchers.

We should test the stuff we have in the Applications menu to see if there’s anything else to fix in some application’s code.
