Do not show icons/applications in the menu

[arcolinuxz]

Distro : ArcoLinux (based on Arch Linux)

The menu sometimes contains applications that will never work or you do not want to show them to the end-user.
In /usr/share/applications/ukui-control-center.desktop there is an example.
This is the important line to hide the application in the .desktop file.

NoDisplay=true

When I try to do the same with other applications in /usr/share/applications (first I tried in ~/.local/share/applications) they remain in the menu.

Following that link I tried also:

NotShowIn=UKUI
Hidden=true

I would like to hide just a handful applications from the menu.
How should I do that? Should I run something to rebuild the menus or clear the cache?

Just set NoDisplay to true. If the application is still displayed, please update the menu to the latest version and try again.
