Hyperpixel 4 Square Touch on Bookworm

Hi all, hope you can help. I’m running a Pi 4 with Bookworm with a Hyperpixel 4 Square Touch. The screen display works perfectly, but I don’t seem to be able to get the touch to work at all. After trying everything else, I also tried the legacy script, but it didn’t work either–I’ve since uncommented everything in the /boot/firmware/config.txt … not sure if this is a common issue, or specific to me, but could use some advice!
