receive mail with nodemailer without setting "Allow less secure apps to access"

Question

I want to ask something about nodemailer, i make code like

Var client = nodemailer.createTransport ({ 
Service: 'gmail',
Auth: {
User: '[email protected]', // Your email address
Pass: '123' // Your password},
Tls: {rejectUnauthorized: false}
});

And this works, but after successful delivery, when I have to receive email messages that have been sent, I need to enable gmail settings like "Allow less secure apps to access". I do not want to set it.

So how do I send emails from [email protected] TO [email protected], without setting "Allow less secure apps to access" and message directly accept in email box !!??? Or any other plugin that should be added ??

THANX;)

Obtain accessToken & refreshToken from Google OAuth2.0 Playground, clientId & clientSecret from Google developer console

const nodemailer = require('nodemailer');
const xoauth2 = require('xoauth2');
var express = require('express');
var router = express.Router();


var smtpTransport = nodemailer.createTransport('SMTP',{
  service:"Gmail",
  auth:{
    XOAuth2: {
      user:'[email protected]',
      clientId: 'your-client-id',
      clientSecret: 'your-cliet-secret',
      accessToken:'your-access-token',
      refreshToken: 'your-refresh-token'

  }
  }
});

router.get('/emaildemo', function(req, res, next) {

  var mailOptions = {
  from: '[email protected]', 
  to: '[email protected]', 
  subject: 'TEST SUBJECTT', 
  text: 'TEST MAIL', 
}; 
smtpTransport.sendMail(mailOptions, function(error, info){
  if(error){
 console.log('Error Occured', error);
  return res.send(error);
  }
  return res.send("mail send successfully");
}); 

});
module.exports = router;
