Firebase not working in electron app when packed using electron packager

I recently built an electron application which utilizes firebase. It works well in the dev environment but when I package it as an exe, the firebase does not work.

How to resolve this ?

My package.json

{
  "name": "powerplant",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "electron": "electron ."
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "electron": "^9.1.2",
    "electron-log": "^4.2.2",
    "firebase": "^7.17.2",
    "html-to-text": "^5.1.1",
    "messagebird": "^3.5.0",
    "msg91": "0.0.6",
    "node-telegram-bot-api": "^0.50.0",
    "sendotp": "^1.2.9",
    "speakeasy": "^2.0.0",
    "springedge": "^1.0.5",
    "twilio": "^3.48.2"
  },
  "devDependencies": {
    "electron-packager": "^15.0.0"
  }
}

My app.js I have imported firebase in my app.js It works perfectly in development, but doesn't work in production.

//  ---------------- IMPORTS ----------------------------------------------

const electron = require('electron');
const {app,BrowserWindow,ipcMain} = electron;

// replace the value below with the Telegram token you receive from @BotFather
const TelegramBot = require('node-telegram-bot-api');
const token = '';
const bot = new TelegramBot(token, {polling: true});

//  ------------- FIREBASE IMPORT AND INITIALIZE ----------------------
var firebase = require('firebase');
const { DataSessionPage } = require('twilio/lib/rest/wireless/v1/sim/dataSession');
var firebaseConfig = {
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    projectId: "",
    storageBucket: "",
    messagingSenderId: "",
    appId: "",
    measurementId: ""
  };
// Initialize Firebase
firebase.initializeApp(firebaseConfig);
var database=firebase.database();

 // this is sorta overall process(Electron App)
let mainWindow;
app.on('ready', () => {

    let senderPhoneNumber
    let senderName;

    console.log('App is now ready!!!');
