G413 Carbon, numlock light.

[hugojmaia]

I just acquired a G413 Carbon and was immediately taken aback by the fact it lacks a numlock LED.
This is at a time where my KDE plasma decided to break the setting that is supposed to turn on numlock on boot.

I was looking through the various options in the command line and haven't identified if it's possible, numlock isn't even listed in the key groupings with the --help-keys option.

What I want to do is to set the numlock LED display to the backlight of the numlock key.
That way I can tell immediately upon looking at my keyboard if numlock is on or not.
