How can i set a localstorage of my Token when google Auth is done?

Question

I tried to add a localStorage of my token when the process is done so i can get it in my react component (let tok = localStorage.getItem('jwtGoogleToken');)

like this :

if (account.enable === true) {
    //send token
    try {
      jwt.sign(
        {
          account,
        },
        "fatboardauthentication",
        // config.secretKey,
        (err, token) => {
          if (err) {
            done(err);
          } else {
            localStorage.setItem("jwtGoogleToken", token); // this wont work
            done(null, token);
          }
          // localStorage.setItem("jwtGoogleToken", token); // this wont work too
        }
      );
    } catch (e) {
      done(err);
    }
  } 

La ligne localStorage.setItem("jwtGoogleToken", token); inside the else will not work, and when i click on my email to connect, i have this screen below and it still like this, charging infinitely : if i move the localstorage outside the else it doesn't work too, i can't see the token in the browser.

this is the complete code :

passport.use(
  new GoogleStrategy(
    {
      // options for google strategy
      clientID:config.oauth.google.clientID,
     clientSecret: config.oauth.google.clientSecret,
     callbackURL: config.oauth.google.redirect,
    },
    (accessToken, refreshToken, profile, done) => {
      // passport callback function
      console.log("passport callback function fired:");
      if (profile !== null) {
        console.log("Contenu de profile :", profile);
        var email = profile.emails[0].value;
        var nom = profile.name.familyName;
        var prenom = profile.name.givenName;
        var googleId = profile.id;
        Account.findOne({ email: email }, async (err, account) => { 
          if (err) {
            console.log("ERRORS 1 ???? ", err);
            done(err);
          }
          if (account) {
            //exist
            if (err) {
              console.log("ERRORS 2 ???? ", err);
              done(err);
            } else {
              //get account
              console.log("currentAccount");
              //check if enable = true
              if (account.enable === true) {
                //send token
                try {
                  jwt.sign(
                    {
                      account,
                    },

                      }

                    }
