Can you have more than one iOS application utilizing the same Firebase back end?

Question

I already have an app out with Apple that uses a specific bundle id and Firebase realtime DB for its back end.

Now instead of creating a new Firebase realtime DB project, I wish to use the same project; main reason being is that there will be information in the existing Firebase project that I will also require in the new application, as well as this should/wouild allow users to login to either app with the same credentials.

Now I want to create a NEW iOS bundle identifier id so that the app is separately purchased from the itunes store but access the same Firebase realtime DB data.... is that possible/allowed?

You can add 30 apps to a single project to share data, as described in the documentation.

Firebase restricts the total number of Firebase Apps within a Firebase project to 30.
