I'll be releasing an oculus standalone version soon so if I have the time I might do a pico version too. Don't get your hopes up though since I don't have a Pico4 and I have no way of fixing anything if it doesn't work.
Wow thanks for the fast response! I'll provide feedback if you ever release for pico4. I have it but not a quest so i can't confirm its easy. but so far developing for it doesnt seem any different compared to the usual. just follow the short official video on importing the pico sdk to unity and you should be done.
