Gran Turismo 7 flags/spotter

Hi

I ordered two Flag LEDs and I want to use them with Gt7 on a console via Simhub. Has anyone managed to do something similar? Does it work? I read on forums that it only changes gears. Is this really the case? Or is there a chance that it also indicates a blue or yellow flag, or if someone is to the left or right of me.

thanks in advance for answers and help
