Led Feedback on Keylab Essential mk3

Im trying to get LED Feedback to work for DAYS.

I have looked through so many Questions here and tried to use velocity Values, i tried using Sysex massages, nothing works.

Can anyone help me, i’ve found a Github where someone posted a Tutorial but i just don’t get it.

I got CSS3 cuz i cant code in the first place, and i’ve been able to do amazing stuff, but i cant even get one thing to light up.

In the attached File, i tried to initialize the DAW connection when the script opens (the guy in the Github wrote that you have to do that first),

then i tried to make Pad 1 be blue when the song is playing (both with sending raw midi data and then using the hex sysex stuff from the github converted to decimal)
