Using a bluetooth mic as default one

[Android Central Question]

Hello there, I'm trying to connect audio devices connected to my Android phone (XIAOMI MI 9) with the pc. I'm using SoundWire app to stream audio from computer via WiFi and I'm successfully receiving data on my phone. At the same time I'm using WO Mic app to stream audio listened by the phone's mic and I can successfully hear the data from my pc.
The next step I would like to reach is to stream audio on my pc directly from a bluetooth earphone. What happen is that the audio streamed by the pc works fine and I can properly hear it on the bluetooth earphone, but trying to stream the mic installed on the bt headset it doesn't work and keep streaming the default microphone's audio. If I use a jack headset it works properly both input and output. Are there any solutions? I tried to use Lesser AudioSwitch app but it didn't work.

I see you got no reply to this question. I have the same question. I use a Bluetooth single-ear headphone with a noise-cancelling mic. I'd like to be able to use the Bluetooth mic in, for example, Whatsapp calls, so that I can leave the phone (a OnePlus 6T) in my pocket. But this doesn't seem to work at all. I have to speak into the phone or I can't be heard, so clearly the BT headphone mic is not being used. I don't know if there's a way to enable it. I too tried the AudioSwitch app without success.
