How to convert URI to File Path from a content page

Hi

I am fairly new to Xamarin. I have used the Plugin.FilePicker.CrossFilePicker to load a file but it is giving me a URI instead of the file path on some devices. How do I convert the URI to the actual file path?

There seems to be a lot of documentation on converting URI to a path but it all seems to be android specific with no examples in a cross platform environment.

Sample Code:

// CONTENT PAGE

public partial class LoadInspection : ContentPage
{
private async Task PickAndShowFile(string[] fileTypes)
{
try
{
var pickedFile = await Plugin.FilePicker.CrossFilePicker.Current.PickFile(fileTypes);

            if (pickedFile != null)
            {
                fn = pickedFile.FilePath;

                if(fn.StartsWith("content://"))
                {
            // convert the URI to a file path
            fn = URIpath????
                }


                if(!fn.EndsWith(".vsi"))
                {
                    await DisplayAlert("Error", "The selected file '" + fn  + "' is not a valid .vsi file", "OK");
                    return;
                }

                inspectionData.loadInspectionFile(fn);

                menuPage = new NavigationPage(new Pages.MainMenu(inspectionData)) { Title = "Main Menu", BarBackgroundColor = Color.FromHex(Models.ColorConfig.barColor) };
                await App.Current.MainPage.Navigation.PushAsync(menuPage);
            }
        }
        catch (Exception ex)
        {
            lblResult.Text = ex.ToString();
            fn = string.Empty;
        }
    }

}

// MainActivity.cs
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;

        base.OnCreate(savedInstanceState);

        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
        ZXing.Net.Mobile.Forms.Android.Platform.Init();

        if (Android.Support.V4.Content.ContextCompat.CheckSelfPermission(this, Android.Manifest.Permission.WriteExternalStorage) != (int)Permission.Granted)
        {
            Android.Support.V4.App.ActivityCompat.RequestPermissions(this, new string[] { Android.Manifest.Permission.WriteExternalStorage }, 0);
        }

        if (Android.Support.V4.Content.ContextCompat.CheckSelfPermission(this, Android.Manifest.Permission.ReadExternalStorage) != (int)Permission.Granted)
        {
            Android.Support.V4.App.ActivityCompat.RequestPermissions(this, new string[] { Android.Manifest.Permission.ReadExternalStorage }, 0);
        }

        LoadApplication(new App());
        Window.SetStatusBarColor(Android.Graphics.Color.Argb(255, 59, 76, 92));
    }
}
