Android Video Chat - I'm Receiving a Video Chat Error But I Have My Permissions Included

Question

I am trying to get a WebRTC video call inside of a webview to show a users video chat on Android devices with the languge being both Kotlin and Java. But when I join the video call, everyone else can see and hear me, but I cannot see and hear them, and their videos aren’t showing up. I get the following error message:

[ERROR:web_contents_delegate.cc(197)] WebContentsDelegate::CheckMediaAccessPermission: Not supported. PlayerBase::stop() from IPlayer stop(164): called with 1438080 frames delivered [ERROR:web_contents_delegate.cc(197)] WebContentsDelegate::CheckMediaAccessPermission: Not supported.

And the Webview Class is as follows:

public class MainActivity extends AppCompatActivity {
    private static final String URL = "https://widgets.bingewave.com/webrtc/7be5952f-65e9-4d99-8e27-00975e8583a7";
    private static final String AUTH_TOKEN = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpYXQiOjE2NjM0MzA4NTUsImV4cCI6MTc1MzQzMDg1NSwiaXNzIjoibG9jYWxob3N0IiwicmVmZXJlbmNlX2lkIjoiM2Y1ZTA4MGMtZjUxNC00ZGVhLWI4NmQtNzExYzEwMTBmNzExIiwidHlwZSI6ImRpc3RyaWJ1dG9yIiwiZGlkIjoiMGM1Nzg3YTEtMWZmYS00MzQ5LWE4OTctYjA4NmFkY2U5MWVlIn0.8MOgvDE_31ARi7fzhVQBQOFwFGK52TTUYLEpjqYV3vs";
    private static final int PERMISSION_REQUEST_CODE = 1001;
    private ActivityMainBinding binding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        WebView webView = binding.webView;

        checkPermissions();

        HashMap<String, String> mapHeader = new HashMap<String, String>();
        mapHeader.put("Authorization","Bearer "+AUTH_TOKEN);
        webView.setWebViewClient(new WebViewClient());
        webView.setWebChromeClient(new WebChromeClient(){
            @Override
            public void onPermissionRequest(PermissionRequest request) {
                request.grant(request.getResources());
            }
        });
        webView.getSettings().setJavaScriptEnabled(true);

        webView.loadUrl(URL, mapHeader);

    }

    private void checkPermissions(){
        if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CAMERA)
            == PackageManager.PERMISSION_DENIED || (ContextCompat.checkSelfPermission(
                MainActivity.this,
        Manifest.permission.RECORD_AUDIO
            ) == PackageManager.PERMISSION_DENIED) ){
            requestPermissions(
                    new String[]{Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO}, PERMISSION_REQUEST_CODE);
        }
    }

    @Override
    public void onBackPressed() {
        if(binding.webView.canGoBack()){
            binding.webView.goBack();
        }else{
            super.onBackPressed();
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if(requestCode == PERMISSION_REQUEST_CODE){
            if ((grantResults.length != 0 &&
                    grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
                Log.i(MainActivity.class.getSimpleName(),"Permission Granted");
            }else{
                Toast.makeText(
                        MainActivity.this,
                "Permission is required to enable feature",
                        Toast.LENGTH_LONG
                    ).show();
            }
        }
    }
}

I made sure to add permissions to my AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.VIDEO_CAPTURE" />
<uses-permission android:name="android.permission.AUDIO_CAPTURE" />

My expectation to to see my video as well as the video of another person in the video chat.
