Passport Facebook strategy in Nodejs doesn't work as of 2023

Question

I have tried to build Passport Oauth login strategy in Nodejs but it seems that it doesn't work as of 2023. Upon clicking login button that triggers standard server API like /auth/facebook/ and setting passport as the middleware, it doesn't even launch FB login popup window, or any window for that purpose.

passport.use(new FacebookStrategy({
  clientID: '**********',
  clientSecret: '************',
  callbackURL: "http://localhost:3000/auth/facebook/cb"
},
  function(accessToken, refreshToken, profile, cb) {
        console.log(profile)
    return cb(null, profile);
  }
));

app.get('/auth/facebook', passport.authenticate('facebook', { display: 'popup' });

app.get('/auth/facebook/cb',  passport.authenticate('facebook'), (req, res, next) => {
  res.send(res.user)
});

I have tried all combinations but nothing happens. Even triggering FB login page manually [as stated on Meta for developers, in that case I got FB login screen (but stanbdard login, without option to confirm data sent) and I managed to receive data into callback API but then the app hangs. Any help would be appreciated, thanks!

if you have configured the autorized redirect uri correctly and your app is live be sure to not have cors issue by using the cors module for nodeJs : https://www.npmjs.com/package/cors note : facebook o auth will not work on local host , try to host your back and front end in a free hosting website and try again .
