gsettings set org.compiz.integrated show-hud doesn't work on 18.04

I want to disable showing HUD and application menus via left Alt.

I've seen on askubuntu that you were able to do that in 14.04 but now (with 18.04) it doesn't work:

gsettings set org.compiz.integrated show-hud "['']"
No such schema “org.compiz.integrated”

The option Key to show the HUD doesn't exist in keyboard settings anymore as stated in another askubuntu answer.

I'm using the Gnome Shell as DE.

For example when using Visual Studio Code I have menu bar being shown every time I press Alt even though I have disabled it or changed the key combination for this.

How can I achieve this then?
