Kakute H743 Wing and Neopixel LED strips

for some reason, I can’t get Neopixel to light up.

I figured out how to light up Neopixel on Servo Channel 13 of Matek H743 WLITE using Lua script.

try doing the same thing on Kakute H743 Wing, with no luck. tried servo 7, 9, 10, 11, 12, 13, 14.
none of them work. doesn’t work without Lua script either using NTF.

anybody able to light up Neopixel using Kakute H743 Wing ?
