Paired devices are not displayed in HomeKit

Today I installed the current phoscon_gateway_headless_2021-12-21 on a Raspberry Pi. I was able to pair an Aqara door window sensor. In the next step I connected the Phoscon gateway to an existing homebridge. There are now two user entries below platform Hue. One for the existing Hue Bridge and another for the Phoscon Bridge. How can I add the Aqara Door Window Sensor to HomeKit now?

Update: I was able to integrate an OSRAM PAR16 50 TW into Phoscon and it was also visible in HomeKit.

Update 2:I did not activate the sensors in the Homebridge-Hue settings under Resource types.
