我有一个脚本，可以根据我们拥有的Google工作表时间表来自动执行日历。它确实可以将事件添加到特定的日历中，但是我想将单个日历添加到脚本中，以及自动将Google组添加为事件的来宾，以便通知像普通的Google日历事件一样消失。

   function scheduleShifts() {
/**
  Task 1) Open the Event Calendar.
**/
var spreadsheet = Spreadsheetapp.getactive();
var calendarID = spreadsheet.getRange("C2").getvalue();
var eventCal = CalendarApp.getcalendarById(calendarID);

/**
  Task 2) Pull each shift information into the code,in
  a form that the code can understand. 
**/
var signups = spreadsheet.getRange("A5:C100").getvalues();
