turn on and off the keyboard backlight with apple script

Hi everyone,

I have a MacBook Air M1 (that doesn't have the function keys for increasing and decreasing the backlight of the keyboard)

I'm searching to manage the luminosity of the keyboard from the keyboard.

I would not to re-map some keys, so I thought to create an Apple script and link it to a keyboard shortcut with the shortcut app.

The problem is that I don't know the apple script language so I'm here to ask some help to write it or to suggest me other options.

Thank everyone that will help me.
