Connexion problem BT with m'y huawei P30

I have a tacx neo 2 that I can connect via bluetooth to my PC and it works.
I would like to connect it to my huawei p30 and when I launch the zwift app, it cannot find my home trainer.
On the other hand, with the tacx application, it connects well in Bluetooth.
So I bought an ant + dongle for Android micro USB with a USB-c adapter. But it doesn’t work on the phone. I don’t know what to do to connect my phone to the home trainer.
Can you help me ?
