• install Linux
• install Gnome
• install some software
• reboot
• these icons are in my menu
• clicking on them does nothing

I know there's probably an explanation for it, which may make sense if you're used to the Linux ecosystem.
But to anyone else, it's just weird that there are buttons in my user-friendly GUI button-clicky desktop environment that make no sense, that I didn't install, and that do nothing when I click on them.

(Yes, I know I can hide them by editing a text file.
Or installing a menu editor that was designed for a version of Gnome from 20 years ago and still works most of the time)
