Google meet, zoom or vetera not working with android webview

How could i use google meet, zoom or any of these videocall apps from a webview?

I'm trying to create video call from a webview in my android app but it says "the browser is not compatible, download chrome, firefox or edge"

I was able to use google meet in the desktop mode in my phone but when i try to use it in the webview it does not let me.

I think the problem is that webview is not using chrome as a browser inside the app and i cant use custom tabs because i need the video inside my app not in an external page.

This is my code now, which is working fine, opening the url in desktop mode but when i try to start the video the error comes up:

class CameraFragment : Fragment() {
    private lateinit var binding: FragmentCameraBinding

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_camera, container, false)
    }

    @RequiresApi(Build.VERSION_CODES.O)
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        binding = FragmentCameraBinding.bind(view)
        if (ContextCompat.checkSelfPermission(
                requireContext(),
                Manifest.permission.RECORD_AUDIO
            ) != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(
                requireContext(),
                Manifest.permission.CAMERA
            ) != PackageManager.PERMISSION_GRANTED){
            val permissions = arrayOf(
                android.Manifest.permission.RECORD_AUDIO,
                android.Manifest.permission.CAMERA
            )
            ActivityCompat.requestPermissions(requireActivity(), permissions, 0)
        }
        webViewSetup()

    }

    @RequiresApi(Build.VERSION_CODES.O)
    private fun  webViewSetup() {
       
        binding.webView.webChromeClient = object : WebChromeClientCustomPoster() {

        }
    }

    }

    }

       override fun getDefaultVideoPoster(): Bitmap? {
            return Bitmap.createBitmap(10, 10, Bitmap.Config.ARGB_8888)
        }

            view.loadUrl(url)

    }

}
