Google Admin Directory API：未授权错误

Question

我有一个脚本，希望我们域的普通用户能够运行。我将其作为文档的附件推出，但是当我的用户运行脚本时，他们会收到此错误：

  

GoogleJsonResponseException：未经授权访问此资源/ API。

我相信是由于这些原因。

var user = Session.getActiveUser().getEmail();

var groupList = AdminDirectory.Groups.list({"userKey":user}).groups;

我认为非管理员用户应该可以将AdminDirectory用于list()和其他只读命令（但不能写入）。但是，我能够找到的文档似乎不适合这个问题。

以上各行的上下文：

function onOpen(e) {
  var ui = DocumentApp.getUi();
  ui.createMenu('Sign Document')
    .addItem('Support Staff Signiture', 'getGroups')
    .addToUi();
}

function getGroups() {
  var user = Session.getActiveUser().getEmail();
  try {
    var groupList = AdminDirectory.Groups.list({"userKey":user}).groups;
  }
  catch (e) {
    DocumentApp.getUi().prompt("There was an error! Report this to tech! Error: " + e);
  }
  var doc = DocumentApp.getActiveDocument();
  var docID = doc.getId();
  
  for (var i = 0; i < groupList.length; i++){
    switch (groupList[i].name) {
