[RN]-JitsiMeet.audioCall using loudspeaker by default

I’m developing jitsi on react native using react-native-jitsi-meet. When I call JitsiMeet.audioCall() by default when call is connected speaker that used is loudspeaker. How I can turn into call speaker?

We have exact but the opposite problem, as mentioned also here. With some devices (using a simple WebView) we are not able to make the audio come from the loudspeaker. Most devices just work fine, but we have some OnePlus 7 devices that activates automatically the callspeker and there is no audio or is low volume.

This happens regardless of the settings. We forced the audio with react-native-switch-audio-output library, but it’s not perfect and it’s not the solution for the problem (headphone case?)
