best way to call the db

[ubresponsive]

I realise this is an auth module but curious on the best way to call the firestore dB without reinstantiating firebase,
for example if I include below, I get FirebaseError: Firebase: Firebase App named '[DEFAULT]' already exists (app/duplicate-app).

const firebaseApp=firebase.initializeApp(firebaseConfig);
const db=firebase.firestore();
export default db;

You should be able to initialize Firebase yourself before initializing next-firebase-auth. See this comment for an example.

I'm also open to suggestions on how we can make this easier, while keeping in mind I'd like this package to stay fairly focused on auth.
