[lock screen] Turn off lights after lock screen

Good morning,
I would like to be able to turn off the LEDs or automatically launch an effect when I lock my screen with the key combination “Windows + L”.
I bought the pro version thinking that the macros could help me but I can’t find what I’m looking for.
Thanks in advance to anyone who has a solution to my problem.
Good day to all
