Per game LED presets

I don't know, maybe I'm missing something, but I cannot find in the docs any guide of how to control leds from a pc. You know like all the other led controllers allow you to illuminate only buttons that are used by the currently launched MAME game.

If you have examples of other projects that do that, it would help. Right now there's no communication from the PC to GP2040 at all other than acting as a standard HID device.
