After getting the code you need to exchange the code for an access token

The code is NOT an access token.

                  }
              );
          
              return
          }
          
          // test for query string parameters
          let { code, error, error_description, scope, state } = req.query;
          
          if (code) {
              // do the oAuth dance and exchange the token for a user token
          
              // first validate the state is valid
              state = decodeURIComponent(state);
          
              if (req.session.state != state) {
                  req.session.error = 'State does not match. Please try again!';
                  res.redirect('/');
                  return;
              }
              // done with the state params
