Not receiving Firebase Push Notifications on Android when app is closed

Hi,
I am using 'FuseJS/Push` and Fuse.Firebase for Firebase integration. When App is running or in the background and I send Push from Firebase console or using Firebase push sending URL https://fcm.googleapis.com/fcm/send, Push is received successfully. But if an app is closed(terminated) and I send Push, a push is not received. It is working on iOS. I tried following JSON formats:

{
  "to" : "<FCM Token>",
  "notification" : {
  	"body" : "This is a Firebase Cloud Messaging sample Message!",
        "title" : "FCM Message",
  },
}

And Data message:

{
  "to" : "<FCM Token>",
  "data" : {
  	"body" : "This is a Firebase Cloud Messaging sample Message!",
        "title" : "FCM Message",
  },
}

Also, I am getting success response when send push with URL but a push is not receiving.

It looks like you’re missing a required alert element in the payload. See docs for details.
