I'm trying to initialize a firebase app but I don't understand how or where to call it.

I have a file name fire.tsx and inside it there's a call to firebase's initializeApp. But now what? How do I include this in my app?

I thought just by adding import { firebaseApp, firebaseAnalytics } from './fire'; to the top of App.tsx it would work but apparently it doesn't. Am I doing this wrong?

import firebase from "firebase";
import "firebase/auth";
import { initializeApp } from "firebase/app";
import { getAnalytics } from "firebase/analytics";


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

const firebaseApp = initializeApp(firebaseConfig); 
export default firebaseApp;

export const firebaseAuth = firebase.auth();

export const firebaseAnalytics = getAnalytics(); 

App.tsx

import { firebaseApp, firebaseAnalytics } from './fire';
