transform a array

Hi there, need some help transforming the array

I have a structure that's coming as below

[
  {
    "statusLine": {
      "protoVersion": "HTTP/1.1",
      "statusCode": 200,
      "reasonPhrase": "OK"
    },
    "entity": {
      "links": [
        {
          "rel": "self"
        }
      ],
      "items": [
        {
          "datetime_beginning_utc": "2023-01-01T00:00:00",
          "pnode_id": 1269364670,
          "total_lmp_rt": 25.611892,
          "marginal_loss_price_rt": 0.132546
        },
        {
          "datetime_beginning_utc": "2023-01-01T01:00:00",
          "pnode_id": 1269364670,
          "total_lmp_rt": 22.818414,
          "marginal_loss_price_rt": 0.150509
        }
      ]
    },
    "original": {
      "priceType": "rt_hrl_lmps",
      "pnodId": "1269364670",
    }
  }
]

 Need to be transformed as below with only from "items" and "original". Need to combine both while adding "original" to all array elements in "items".

Any help is greatly appreciated.

Thanks
