Facebook Graph API-从对话中获取用户个人资料

Question

by using Facebook Graph API I can fetch the conversations between users and my page. One of the returned conversations looks like this:

{
  "message": "message content",
  "from": {
    "name": "My Page's Name",
    "email": "198301820627381@facebook.com",
    "id": "198301820627381",
  },
  "to": {
    "data": [
      {
        "name": "John Doe",
        "email": "396169264164870@facebook.com",
        "id": "396169264164870",
      }
    ]
  },
  "id": "m_mid.$cAADurJ0X8UhnJ3tfxVg9jYXJW5fp"
}

I see that I got the user's id field. How can I fetch this user's profile (first name, last name, profile pic) base on this field ? (or is there another way ?)
I followed the Graph API's User Reference but all I got are the user's id and name (which I already have from the returned conversation).

profile_pic仅适用于PSID（Messenger机器人事件），对于ASID，请仅使用picture字段
