[HELP] how to configure gnome-shell to show keyboard backlight (and others) ?

Hi,

I needed to change my machine to a new one (tuxedo gen9), and I quickly installed my distro of choice (manjaro-gnome), and configured it as the old machine (I am very conservative on this... I do not like the change as it introduces some friction in my workflow... I even have the same wallpaper from the last 10 years, heh :P).

Turns out, I am unable to "see" some options of the gnome-shell that were present in my older machine:

• keyboard backlight regulation (and it works, as I am able to regulate it with fn+space)
• background apps

I would like to bave them back... any hint on what I can be missing ?
