How to send Upstream FCM messages from iOS? (from 2017) shows that Firebase used to have an option to send messages from iOS using Messaging.messaging().sendMessage().

It seems that this feature is available for Android as documented in https://firebase.google.com/docs/cloud-messaging/android/upstream
