Support of these kind of devices on Wayland is still a bit of hit and miss and WiP AFAIK. I have two devices: a cheapo Wacom Intuos something that didn’t work at all a month ago, but now works out of the box, and an XP Pen tablet that is recognised, but I can’t configure the drawing area.
I guess what I am saying is “patience”. Things are improving every day, but not all devices are totally supported yet.
