var cameraProviderFuture = ProcessCameraProvider.GetInstance(context) ?? throw new CameraException($"Unable to retrieve {nameof(ProcessCameraProvider)}");
cameraProviderFuture.AddListener(new Runnable(() =>
{
var cameraProviderInstance = cameraProviderFuture.Get();
if (cameraProviderInstance is not AndroidX.Camera.Core.ICameraProvider androidCameraProvider) // this is true, but must be false
{
cameraFutureCts.SetResult();
return;
}

var extensionsManagerFuture = ExtensionsManager.GetInstanceAsync(context, androidCameraProvider);
extensionsManagerFuture.AddListener(new Runnable(() =>
{
var extensionsManager = (ExtensionsManager)extensionsManagerFuture.Get()!;
if (extensionsManager.IsExtensionAvailable(cameraSelector, extensionMode))
{
cameraSelector = extensionsManager.GetExtensionEnabledCameraSelector(cameraSelector, extensionMode);
}

cameraFutureCts.SetResult();
}), ContextCompat.GetMainExecutor(context));
