[SOLVED] How do I navigate from an Android Activity to a Xamarin Forms ContentPage?

How do I navigate from an Android Activity to a Xamarin Forms ContentPage?

I'm developing an application that uses an online payment. I open the link, for the payment, in a browser using: Device.OpenUri(Uri);. When the user has finished paying for his order he gets redirected to an Android Activity using a custom URL scheme:

[Activity(Label = "Urlentryclass", ScreenOrientation = ScreenOrientation.Portrait, Icon = "@drawable/icon",
        MainLauncher = false, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    [IntentFilter(new[] {Android.Content.Intent.ActionView},
        DataScheme = "test",
        Categories = new[] {Android.Content.Intent.CategoryDefault, Android.Content.Intent.CategoryBrowsable})]
 public class Urlentryclass : FormsAppCompatActivity
...

How do I navigate to a certain Forms content page from this activity? I try to open a certain page using the following code example (It's done by using an Event Handler).

Navigation.PushAsync(new NavigationMenu(sisowStatus, modelStatus)).ConfigureAwait(false);

Followed by this.finish();

Hower, the view that's being showed is the last view that was opened before the browser shows. It seems that Navigation.PushAsync doesn't affect the view that's being showed. I've try PopAsync, PopToRootAsync but nothing seems to be working.

For those that are interested in the Event Handler, here it is:

public static class PaymentNavigationHelper
{
    public delegate void PaymentExecutedHandler(string sisowStatus, string orderStatus);
    public static event PaymentExecutedHandler OnPaymentExecuted;

    public static void PaymentExecuted(string sisowStatus, string orderStatus)
    {
        OnPaymentExecuted?.Invoke(sisowStatus, orderStatus);
    }
}

I'm subsribing to the event on the Content Page where I'm starting the payment:

 PaymentNavigationHelper.OnPaymentExecuted += (sisowStatus, modelStatus) =>
 {
     Navigation.PushAsync(new NavigationMenu(sisowStatus, modelStatus)).ConfigureAwait(false);
 };

In the activity which handles the payment url, the following code is being used:

PaymentNavigationHelper.PaymentExecuted(status, test.Model.FirstOrDefault().Status);

Any advice is highly appreciated.
