How do I rename the package name in expo EAS build?

Hey expo team, I have just tried using expo eas build and it worked fine, but now I need to change my android package name, so I can integrate with it my existing firebase project.

expo-cli 4.13.0
expo: managed workflow
expo-sdk: 43.0.2

Is this what you’re looking for?

In the managed workflow you set the package name in the key in app.json.
