How to use APN Auth Key.p8 certificate in Firebase console

Question

How do you use Firebase to send push notifications using the new P8 file for Apple Auth Key?

I understand how to use the old Apple p12 files to send push notifications, but would like to upgrade to the new Auth Key.

Here is the only resource I could find (does not answer the question): How to use the new Apple.p8 certificate for APN in the firebase console

Answer 1

Now you can download the .p8 file (APNs auth key) in your Firebase console on the same page where you download .p12 (APN certificates).
