As I have not used firebase realtime DB only using firestore, if I disable the realtime db from firebase console, it stops the react app from running after login is success. I do have databaseURL property in firebase config. So how to detach the realtime firebase db from the react app. So that even if I disable realtime db from firebase it shouldn't affect my app.

import app from 'firebase/app';
import 'firebase/auth';
import 'firebase/database';

const firebaseConfig = {
  apiKey: "",
  authDomain: "",
  databaseURL: "",
  projectId: "",
  storageBucket: "",
  messagingSenderId: "",
  appId: ""
};

const db = app.database();
