I need to add push notifications to an app that is developed with Ionic Framework and Capacitor. I already created the project in Firebase and it gives me a google-services.json file which must be put in the root of the project. The problem is that there is already a google-services.json file because there is already a Google Analytics project configured, and there is no documentation explaining how to make both files coexist from Ionic.

I hope to integrate both (or more) google services like Firebase, but if each new Firebase project returns a google-services.json file I don’t know how to configure them at the same time.
