LaunchcontrolXL LED

[Solncev_]

Hey guys...help me please. I try to make my first controller script for launch control XL.
I use Moss youtube guide and arrive to 6 part.


Everything work well BUT... I can't get the buttons to glow. launch control XL has 16 LED buttons.
I can't make the buttons corresponding to the tracks in Bitwig receive a glow signal.

unfortunately Moss showed how to make the transport buttons glow and yes it works. I'm too noob, but I'm very interested in trying and making it.
I'm pretty bad at understanding how the API works, I'm sure that's the problem.
If it's not difficult for you, could you tell me how to do this ...

thanks.
