pairing roller trainer with ant+

Hello!

I have the "Elite Turbo Muin" roller trainer, which should transmit data such as speed, cadence and power via Bluetooth and ANT +, which unfortunately does not work ...

... when searching for sensors ("search all sensors") it appears under the name "Elite Misuro B +", but cannot be linked, same problem when looking for Smart-Trainer ...

A friend says he was able to pair the trainer with one of his Garmin bike computers (from the Edge series, I think). Shouldn't the ANT + standard also work with a Fenix ​​6pro ?!

Thank you for further feedback!
