Bluetooth Headset Not Working with MS Teams

Hope this can help someone going through a similar issue. Issue : I used MS Teams for meetings with colleagues and for some reason my Bluetooth headphone (Mpow H7) stopped working. I use it as speaker and there was just no sound coming out. It used to work before, so I’m not quite sure what went wrong. I’m suspecting some update could have change some setting or changed something. Note that the headphone works perfectly well with Zoom and other applications.
