How to get user from comment on page posts use feed

I got the comments list from the feed, but I could not get their user name and avatar, I used the graph explorer and there were no fields to retrieve the user information that was commented.

I tried, but it does not work. {page_id}/feed?fields=id,comments{id,message,created_time}

Comment Id also doesn't support getting user information. 448052816017010_448055412683417/?fields=message

// My result

"data": [
      {
        "id": "448052816017010_448055412683417",
        "message": "TYM TYM",
        "created_time": "2019-06-24T07:20:22+0000"
      }
    ] ...

Is there a way to get user or user id, or do I need to grant any permissions?
