authorization in GROUP share level

[user-GitHub-user]

hello, i use ranger for authorization, in group share level i want fine-grained access control for session user, I don't quite understand the meaning in the document. Do I need to modify the code of kyuubi to support this function, or should I modify the code of spark? Does kyuubi have a configuration to support it directly?

AFAICR, kyuubi session user will be populated by the Kyuubi server automatically

In my cases (I use Ranger), the policy defined for kyuubi session users could work. But those defined for groups doesn't, even if I had use the primary group name to create a user in Ranger and defined policies for them
