[Plugin] Phonegap -plugin-push v.1.x in Firebase for support

Because of some factors, I need to use the phonegap-push-plugin v1.x version.
I use ionic, plugin to add phonegap-push-plugin@1.10.4.
I use Firebase to send a message and I never receive any messages.

I have tried the phonegap-push-plugin v.2.x version,
I can receive the firebase message.
So phonegap-push-plugin v.1.x version, it is determined to be unusable,
Did i get that right ?
