How to navigating to a specific page on Push Notification tap

Issue

I am developing firebase push notifications in Xamarin.Forms using FirebasePushNotificationPlugin. Somehow I am getting notifications for android project in Application file, along with data

CrossFirebasePushNotification.Current.OnNotificationReceived += (s, p) =>
{
    //System.Diagnostics.Debug.WriteLine("NOTIFICATION RECEIVED", p.Data);
    var data = p.Data; //Dictionary type
};

Based on above data how can I navigate to specific Page except MainPage()?

This is my App.xaml.cs file in Shared project

public App()
{
    InitializeComponent();
    MainPage = new MainPage();
}

MainActivity.cs class in Android project

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);
        global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
        LoadApplication(new App());

        FirebasePushNotificationManager.ProcessIntent(this, Intent);
    }

    protected override void OnNewIntent(Intent intent)
    {
        base.OnNewIntent(intent);
        FirebasePushNotificationManager.ProcessIntent(this, intent);
    }
}

Edit 1: According to @G.Hakim answer below code always opening NotificationsPage without sending notification(Except first time. Only first time opening MainPage when executing app). If I click on app it always goes to NotificationsPage instead of MainPage.

MainActivity.cs

protected override void OnCreate(Bundle savedInstanceState)
{
    TabLayoutResource = Resource.Layout.Tabbar;
    ToolbarResource = Resource.Layout.Toolbar;

    base.OnCreate(savedInstanceState);
    global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
    LoadApplication(new App(false,null));

    FirebasePushNotificationManager.ProcessIntent(this, Intent);
    CrossFirebasePushNotification.Current.OnNotificationOpened += (s, p) =>
    {
        System.Diagnostics.Debug.WriteLine("NOTIFICATION RECEIVED", p.Data);
        var data = p.Data;
        DependencyService.Get<IToast>().DisplayTost("opened notifications");
        LoadApplication(new App(true, p));
    };
}

App.xaml.cs

public App(bool hasNotification = false, object notificationData = null)
{
    if (hasNotification)
    {
        MainPage = new NotificationsPage();
    }
    else
    {
        MainPage = new MainPage();
    }
}

Solution

This issue has been solved by sending color key from notification payload.

CrossFirebasePushNotification.Current.OnNotificationOpened += (s, p) =>
{
    if (p.Data.ContainsKey("color"))
    {
        Device.BeginInvokeOnMainThread(() =>
        {
            Xamarin.Forms.Application.Current.MainPage.Navigation.PushModalAsync(new NotificationsPage()
            {
                BackgroundColor = Color.FromHex($"{p.Data["color"]}")
            });
        });
    }
};

Note: Above code is working when app open & in background. Not working when app closed. For more information visit this ticket.
