RestHeart Response without metadata

How can I get a RestHeart response without metadata when I query a collection? (like "_embedded", "_id", "_returned") Example:

https://restheart.url/test

{
  "_embedded": [
    {
      "_id": "5c530d6381e931ba5992ea35",
      "isActive": true,
      "age": 35
    },
    {
      "_id": "5c530d63602cca9789a4ddb0",
      "isActive": true,
      "age": 36
    },
    {
      "_id": "5c530d63275c5a64b643ed4a",
      "isActive": true,
      "age": 37
    },
    {
      "_id": "5c530d63eddff83681b51ebf",
      "isActive": true,
      "age": 27
    },
    {
      "_id": "5c530d63d6ed461d02948520",
      "isActive": true,
      "age": 30
    },
    {
      "_id": "5c530d639ef0e13b0cb6f3d7",
      "isActive": true,
      "age": 24
    }
  ],
  "_id": "test",
  "_returned": 6
}

The answer is using the QueryString parameter "np". Documentation: https://restheart.org/learn/representation-format/

    },
    {
