🚀 Feature: Simplify FCM integration

### 🔖 Feature description

Having something like:

`await account.createFcmPushTarget(FirebaseConfigHere);`

### 🎤 Pitch

Instead of installing, configuring, initializing, etc the Firebase SDK, some direct function that allows generating an FCM token will simplify the entire experience, mainly for users that never used FCM.
