WebView with Audio/Video permissions

Hey. We have a web-chat with video and audio communications. At the time of the call, permission requests occur. But just not in the web view. If you do the resolution of audio / video at the application level, then this of course will not help. If you call the method navigator.mediaDevices.getUserMedia ({audio: true, video: true}) through the injection of JS, then there is no result either (undefined). Does this library solve it somehow?

<CustomWebView
      originWhitelist={['*']}
      ref={webviewRef}
      allowsFullscreenVideo
      allowsInlineMediaPlayback
      heightDevice={height}
      source={{
        uri: 'https://webcamtoy.com/ru/',
      }}
    />

This is problem for Ios and Android, both platform
