In Short, I want to return the custom jwt token to the frontend when the OAuth successfully completes. Can someone please help me achieve this? Thanks in Advance.

After having a lot of search over the internet, finally I found the solution for this. To achieve this, you have to use the req argument in the callback and attach the user data with it as shown in the screenshot below:

and then in the callback, you can get the user from req._user

Passport google strategy Code:

 passport.use(new GoogleStrategy({
    clientID: config.googleOAuth.clientId,
    clientSecret: config.googleOAuth.clientSecret,
    callbackURL: `${config.endpoints.apiUrl}/user/gmail/oauth`,
    passReqToCallback: true
    },
    async function (req, accessToken, refreshToken, profile, done) {
      const profileJson = profile._json;
      const userData = {
        username: profileJson.email,
        firstname: profileJson.given_name,
        lastname: profileJson.family_name,
        picture: profileJson.picture,
        authType: 'oauth'
      }
      const user = await userCtrl.createOrUpdateUser(userData);
      req._user = userData;
      return done(null, user);
    }))

Callback Code:

 const OAuthCallback = async (req, res, next) => {
// function called after successfull oauth
console.log(req._user)
 }
