kwumsy K3 touchscreen keyboard

Hello
I have a problem with my new keyboard, or rather the touchscreen. At first glance, the device works wonderfully, but unfortunately I cannot assign the touchscreen to the screen on the keyboard as intended. The problem starts with the fact that the keyboard with the screen is not always attached to the system. As I also want to use this for my notebook. Unfortunately, this means that fixed mapping via the X11 config is not possible.

I have already created the command for the assignment and it also works manually.

xinput --list | grep BJYP-K3 | cut -d '=' -f 2 | cut -f 1 | xargs -i xinput --map-to-output {} HDMI-0

Unfortunately, I have not managed to automate the assignment on my system with Cinnamon and lightdm.

my udev rule did not work...

SUBSYSTEM=="usb",ATTRS{idVendor}=="28e9",ATTRS{idProduct}=="028a",ACTION=="add", RUN+="xinput --list | grep BJYP-K3 | cut -d '=' -f 2 | cut -f 1 | xargs -L1 xinput --map-to-output {} HDMI-0"

and I had no luck with ~/.xinitrc and ~/.xsession.

I would be very grateful for any suggestions
