Facebook APP 权限审核遭拒

The user_groups permission is only approved for apps that let people use Facebook on platforms where Facebook is not already available.
If you're building an app on Android and iOS, for example, you won't be approved for this permission. Web, Desktop and TV apps will also not be granted this permission.

被拒绝的详细说明，总之facebook就是不给你这个user_group权限啦 = 3 =

我很好奇IFTTT是怎么拿到这个权限的。
