   npm install @react-oauth/google

   // App.jsx
   import { useState } from "react";
   import { GoogleOAuthProvider, GoogleLogin } from "@react-oauth/google";

   function Homepage() {
     const [authData, setAuthData] = useState(null);

     const gContainer = {
       display: 'flex',
       flexDirection: 'column',
       alignItems: 'center',
       marginTop: '50px'
     };

     return (
       <GoogleOAuthProvider clientId={"YOUR_GOOGLE_CLIENT_ID_HERE"}>
         <div>
