Using an external touchscreen on Ubuntu 22.04 Wayland problem

I have an external AOC 16T2 touchscreen, which is recognized as an touchscreen.

In X11 this works fine in extended desktop/join displays after mapping the touch input to the external screen.

 xinput map-to-output <xinput-id> <xrandr-id>

BTW I'm not sure why this is not the default, because having to touch the external monitor to click on a link on the first monitor does not make any sense IMHO.

In Wayland this does not work. xinput (wrapper) is not recognizing the monitor anymore, so there is no <xinput-id>

The touchscreen is still working, but a click on the secondary screen is recorded as a click on the first screen, which is wrong.

libinput is listing the device:

Device:           Melfas LGDisplay Incell TouchKernel:           /dev/input/event13Group:            5Seat:             seat0, defaultSize:             341x195mmCapabilities:     touch Tap-to-click:     n/aTap-and-drag:     n/aTap drag lock:    n/aLeft-handed:      n/aNat.scrolling:    n/aMiddle emulation: n/aCalibration:      identity matrixScroll methods:   noneClick methods:    noneDisable-w-typing: n/aAccel profiles:   n/aRotation:         n/a

How can I fix the input mapping problem in the default Ubuntu 22.04 Wayland?
