Mic and Camera Permission issue

I am using this plugin in my project using prebuilt AARs and ensures granting android permissions before creating webview object but mic and camera are not working.
here is my code
public void OpenMicTesting()
{
if (webView == null)
{
canvas.SetActive(false);
webView = (new GameObject("WebViewObject")).AddComponent();
webView.SetCameraAccess(true);
webView.SetMicrophoneAccess(true);
webView.SetInteractionEnabled(true);
webView.Init(transparent: false, enableWKWebView: true, cb: (msg) => Debug.Log("WV MSG: " + msg));
webView.SetMargins(0, 0, 0, 0);
webView.SetVisibility(true);
Screen.sleepTimeout = SleepTimeout.NeverSleep;
}
string url = "https://webrtc.github.io/samples/src/content/devices/input-output/";
webView.LoadURL(url);
webView.SetVisibility(true);
}
public void OpenCameraTesting()
{
if (webView == null)
{
canvas.SetActive(false);
webView = (new GameObject("WebViewObject")).AddComponent();
webView.SetCameraAccess(true);
webView.SetMicrophoneAccess(true);
webView.SetInteractionEnabled(true);
webView.Init(transparent: false, enableWKWebView: true, cb: (msg) => Debug.Log("WV MSG: " + msg));
webView.SetMargins(0, 0, 0, 0);
webView.SetVisibility(true);
Screen.sleepTimeout = SleepTimeout.NeverSleep;
}
string url = "https://webrtc.github.io/samples/src/content/getusermedia/gum/";
webView.LoadURL(url);
webView.SetVisibility(true);
}
The android permissions are called in awake as follows
void Awake()
{
if (!Permission.HasUserAuthorizedPermission(Permission.Camera))
Permission.RequestUserPermission(Permission.Camera);
if (!Permission.HasUserAuthorizedPermission(Permission.Microphone))
Permission.RequestUserPermission(Permission.Microphone);
}
the permission i grant but still not working
my testing device is redmi note 14.

please guide me!!!!!!!!

Start by reproducing the issue on the Redmi Note 14 using the shown Awake permission flow and the OpenMicTesting/OpenCameraTesting entry points. Check the WebViewObject calls and the two WebRTC sample URLs, then compare the permission state and runtime behavior; done means microphone and camera access works in both tests.
