I am using rocket chat websocket. In those messages when we get the message of "user added" or "removed" I want the user's full name

wss://[ABC.DOMAIN.COM]/websocket

I am using websocket of rocket chat.

This is one of the message from the list of messages response the websocket provides.

{
  "_id": "some id",
  "t": "au",
  "rid": "some id",
  "ts": {
    "$date": 1663823165892
  },
  "msg": "7d4e5ab4-34ca-11ed-b29a-7cc2c61d171e",
  "u": {
    "_id": "some id",
    "username": "svc_site_prod",
    "name": "svc_site_prod"
  },
  "groupable": false,
  "_updatedAt": {
    "$date": 1663823165902
  }
}

It uses t = "au" for added user and "ru" for removed user. The real user added is present in "msg". But it only shows the username of user who is added or removed. I want the full name of this user.

I know I can just make another request to find the user's info by api. But what I want is to get the details in this response.

Edit: the headers of request

{
  "msg": "method",
  "method": "loadHistory",
  "id": "1",
  "params": [
    "AyzhtTJiE6YG3cnfA",
    null,
    50,
    null
  ]
}
