IC8 ICG pairing with Fenix 7s Pro

Hi, I have an ICG IC8 bike that has Bluetooth, Ant+ and power meters. 

I tried to pair the smart trainer but it is not appearing as a sensor. The only things I see to be paired are a cadence sensor, power, and HR (no clue the last one what it is).

How should I actually pair it with my fenix 7s to have the data being displayed while selecting indoor bike as an activity? Any idea?
