Annepro2 bluetooth recognition does not work

I’ve setup my annepro2 keyboard but was unable to make the keyboard appear as a bluetooth device. I’ve found the following old post:

but that does not solve my issue. I’ve also updated the keyboards firmware. It is something within linux/manjaro as my hand can detect it. I’m using obinskit and followed the commend adding the udev rule to no vail. Can ayone provide me some tips?
