Can't find "Show Desktop" function in ParrotOS KDE

Hi guys, What is the program or command in ParrotOS KDE, that allows from cli to minimize all the programs in the desktop? Maybe there is a shortcut for that? I’ve tried CTRL+ALT+D without success.
and “wmctrl -k on” It is not working neither

Thanks

Using
Parrot OS 5.0 KDE

I just use the Plasmoid “Show Desktop” which I put to the right of my clock.

Or you can set a keyboard shortcut as explained here: kde4 - Show KDE Plasma desktop like in Windows 7 - Ask Ubuntu

Ctrl+F12 is the default.

Thanks, CTRL + F12, working OK, solved
