How can i use passportJS strategy with ApolloServer

import express from 'express';
import { prisma } from '@peerpush/db';
import { ApolloServer } from '@apollo/server';
import { startStandaloneServer } from '@apollo/server/standalone';
import { typeDefs } from './src/graphql/schema/typeDefs.js';
import { resolvers } from './src/graphql/resolvers/index.js';
import passport from 'passport';
import { Strategy as GitHubStrategy } from 'passport-github2';
import session from 'express-session';
import dotenv from 'dotenv';

(async function () {
  dotenv.config();
  const app = express();
  const server = new ApolloServer({
    typeDefs,
    resolvers,
  });
  app.use(session({
    secret: 'keyboard cat',
    resave: false, // don't save session if unmodified
    saveUninitialized: false, // don't create session until something stored
  }));

  app.use(passport.authenticate('session'));
  app.get('/auth/github',passport.authenticate('github'));

  passport.serializeUser(function(user, done) {
    done(null, user);
  });

  passport.deserializeUser(function(obj, done) {
    done(null, obj);
  });

  passport.use(new GitHubStrategy({
      clientID: process.env['clientID']!,
      clientSecret: process.env['clientSecret']!,
      callbackURL: "/oauth2/redirect/github"
    },
    function(accessToken, refreshToken, profile, done) {
      console.log({accessToken, refreshToken, profile});
    }
  ));

  app.get('/login/federated/github', passport.authenticate('github'));

  app.get('/oauth2/redirect/github', passport.authenticate('github', {
    successReturnToOrRedirect: '/',
    failureRedirect: '/login'
  }));

  const { url } = await startStandaloneServer(server, {
    listen: { port: 4000 },
  });
  console.log(` Server ready at: ${url}`);

  app.listen(4001,() => console.log('server'));

})().then(async () => {
  await prisma.$disconnect();
}).catch(async (e) => {
  console.error(e);
  await prisma.$disconnect();
  process.exit(1);
})
