Back facing camera in android webview

I made a simple android app which uses a WebView to display Jitsi Meet desktop site on mobile.

I’m now trying to get android send video from the back-facing camera.

Changing the CAMERA_FACING_MODE from USER to ENVIRONMENT in Jitsi Meet code doesn’t seem to work.

Should I find a way of selecting the back-facing camera as preferred from the webview app or should I investigate further inside Jitsi Meet code?

Thanks in advance.
