Huion tablet buttons not detected in KCM

Hello i just switched to bazzite and wanted to start using my huion drawing tablet, the kamvas pro 20. For this i installed the OpenTabletDrivers via the ujust command and blacklisted the hid_uclogic via” rpm-ostree kargs --append=modprobe.blacklist=hid_uclogic“ for it actually to be recognized in the tablet kcm with pen pressure support.

now im i want to adjust the physical buttons that are on my tablet but they wont show up in the plasma KCM, could someone help with this?
