如何在chrome扩展/应用程序中从G Suite中检索当前登录用户的组织单元？

"oauth2": {
  "scopes": [
    "https://www.googleapis.com/auth/admin.directory.user.readonly"
  ]
}

<script src="https://apis.google.com/js/client.js"></script>

function authenticate() {
  return gapi.auth2.getAuthInstance()
    .signIn({ scope: "https://www.googleapis.com/auth/admin.directory.user.readonly" })
    .then(function() { console.log("Sign-in successful"); },
          function(err) { console.error("Error signing in", err); });
}

function loadClient() {
  gapi.client.setApiKey('YOUR_API_KEY');
  return gapi.client.load("https://content.googleapis.com/discovery/v1/apis/admin/directory_v1/rest")
    .then(function() { console.log("G Suite Admin SDK client loaded for API"); },
          function(err) { console.error("Error loading G Suite Admin SDK client for API", err); });
}

function execute() {
  return gapi.client.admin.users.get({ 'userKey': 'me' })
    .then(function(response) {
      var organizationUnit = response.result.orgUnitPath;
      console.log("Organization Unit:", organizationUnit);
    },
    function(err) { console.error("Error retrieving organization unit", err); });
}

gapi.load("client:auth2", function() {
  gapi.auth2.init({ client_id: 'YOUR_CLIENT_ID' });
});

<button onclick="authenticate().then(loadClient).then(execute)">Retrieve Organization Unit</button>
