pg_hint_plan whether support for hints for group by method(hash/sort)?

[ZhiXingHeYiApple]

I have reviewed the documentation and issue list, but I couldn't find how to use the pg_hint_plan extension to force my group by SQL query to use hash aggregation. Like /*+ use_hash_aggregation*/ hint will throw error about pg_hint_plan: hint syntax error at or near "use_hash_aggregation"
