AndroidTV Binding [3.2.0;4.2.0)

I’m having problems executing the PIN Code Process on my openHAB 4.2.2 (running on Raspi 5 / Docker) with my Xiaomi Laser Projector 150’’ (running Android TV version 9). When executing the process, no code shows up on the screen . Does anyone have an idea?

I‘ve included more details here (just noticed that all issues regarding the binding appear to go in here).
