Does firebase set apns-push-type header automatically?

Question

According to changes in iOS 13 for APNS, silent push notifications require additional header (apns-push-type).

I use Firebase as a mediator between backend and mobile, and I'm wondering if Firebase sets mentioned header automatically when content-available property is set to true.

It is already happening in AWS, as mentioned here.

Can I check somehow in iOS if this header was passed to silent push notification?

I've tested on my devices and everything is working after I updated Firebase dependency to the newest version, even in background. But still I don't have any proof how the header looks like.

After digging around a little bit and checking how some open source projects updated their code, here's an example on how to add apns-push-type to Firebase Admin Node:

(I'm using multicast, so your solution might differ.)

const message = {
  priority: 'high',
  sound: 'default',
  notification: {
    title: 'Message Title',
    body: 'Message Body',
  },
  android: { ... },
  apns: {
    headers: {  // Add these 3 lines
      'apns-push-type': 'alert',
    },
    payload: {
      aps: {
        badge: 1,
        sound: 'default',
      },
    },
  },
  tokens: [ ... ],
};

admin.messaging().sendMulticast(message);

I only had a few notifications failing so I haven't been able to fully confirm that the problem is solved yet.
