Motion detection as trigger for lights

I would like to use the motion sensor in one of my cameras (eufyCam-2C) to trigger switching on homekit enabled lights (automation via the apple home app).
It works if the homekit setting for the camera is set to „stream and record“. However, it does not work in the setting that I would like to use: „activity tracking only“.
This seems to be a „bug“. Any idea how I can solve this?


I dont see a response but have you found out if you can do so?
