Php Google API日历403权限不足错误

早些时候，我发送了一些请求来获取日历列表，结果一切正常。但是，当我想用另一个作用域（Google_Service_calendar:：calendar）创建辅助日历时，它会处理这个403 insufficientPermission错误

这是密码

<?php
   require_once 'vendor/autoload.php';
   session_start();

   $client = new Google_Client();
   $client->setAuthConfig('client-secret.json');
   $client->addScope(Google_Service_Calendar::CALENDAR);
   if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
         $client->setAccessToken($_SESSION['access_token']);
         $service= new Google_Service_Calendar($client);
         $calendar = new Google_Service_Calendar_Calendar();
         $calendar->setSummary('CalendarioProper');
         $calendar->setTimeZone('Europe/Madrid');

         $createdCalendar = $service->calendars->insert($calendar);

         echo $createdCalendar->getId();

     } else {
         $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] .'/oauth2callback.php';
         header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
     }
   ?>

我正在用XAMPP通过本地主机做所有事情，也许这与我的问题有关？

谢谢，我的英语不是最好的抱歉。谢谢，我的英语不是最好的抱歉。
