How to use Ionic+Capacitor to register Push Notifications via Amazon SNS

Any guide on how to properly use ionic and capacitor to acquire tokens for SNS? I’ve seen the PushNotifications plugin but I’m not sure what “register” does? Do i have to setup my firebase and apn if im only using Amazon SNS?

Any guide/tips or overview steps will be useful.

Thanks
