从服务人员访问全局ZoomMtg对象

Question

我想从我的服务工作者那里调用ZoomMtg API中的本机方法来做一些事情，这意味着根据用户的接受动作来打开一个缩放会议。我了解我无法从服务工作者访问全局缩放对象，因此必须使用postMessage API。任何帮助将不胜感激。因为我不知道该怎么办。

let fldMeetingID = null;

// Remove SDK push handler
self.removeEventListener('push', self.OneSignalWorker.onPushReceived);
// Register our own custom handler
self.addEventListener('push', (event) => {
  if (event.data) {
    const data = event.data.json();
    const notification = self.OneSignalWorker.buildStructuredNotificationObject(data);
    if (notification.data.isCanceled !== 1) {
      fldMeetingID = notification.data.fldMeetingID;
      const options = {
