Expo Push Server

I’ve read that the Exponent Push Notification doesn’t work with external backends, like Firebase. What am I supposed to use for this? Is there a push server that I’m supposed to deploy myself? What about a cloud service?

All I’m looking for is a nudge in the right direction. Thanks!

I’ve seen a couple mentions about an Expo push service, but I can’t find anything clearing up what that is or how to use it.

Did you read this https://docs.expo.io/versions/latest/guides/push-notifications.html?
