Firebase Notification Message doesn't work after closing app

I'm trying to test pushing notification from Firebase Cloud Messaging this working fine in debug mode but in Release mode or closing app doesn't work
I Enabled Proguard and multidex but unforunatly it doesn't work for me I used CrossGeeks Plugin for this
and this is my code in android

 //Handle notification when app is closed here
            CrossPushNotification.Current.OnNotificationReceived += async (s, p) =>
            {
                await Helpers.Notify.SendNotification("Firebase", p.Data.ToString());
            };

Notify.cs

public class Notify
    {
        public static async Task SendNotification(string title, string body)
        {
            CrossLocalNotifications.Current.Show(title, body);
        }
    }

Also I know about Difference between data message and Notification message I want to test if the data Message is working fine from
Firebase.consol but no way

finally i test from postman
