Google 文档 Add-On：Permission-related 错误 "This App is blocked"

Question

我在脚本编辑器中创建了一个 Google 文档 Add-On。当我尝试在 Google 文档中启动 Add-On 时，它会在选择并登录 Google 帐户后显示此屏幕：

不确定是否相关，在应用程序脚本的概述部分，项目 OAuth 范围是：

连接到外部服务
在 Google 应用程序 Google 的提示和边栏中显示和运行 third-party 网页内容
查看和管理已安装此应用程序的文档

我该如何解决这个问题？或者我该如何调试？

脚本(code.gs)如下:

这里是appsscript.json的内容：

{
  "timeZone": "Asia/Shanghai",
  "dependencies": {
  },
  "exceptionLogging": "STACKDRIVER",
  "runtimeVersion": "V8"
}

如果您打算将该项目用作附加组件，您应该 set the "oauthScopes" explicitly in the manifest file (appsscript.json)。
