IOS/Android notifications with FCM

Hi there,

I’ve read the documentation on “Using FCM” and “Push Notifications”. While it’s clear that FCM can only be used in Android, my question is, if I send notifications through FCM, will I be able to handle these with APNS on IOS, while using FCM client for Android?

This means to keep using FCM as a backend service for sending notifications, just use a different client on IOS/Android.

Or I will have to use the Expo notifications server/library?
