Jolt transformation to remove nested array

Could you please assist me in performing a Jolt transformation to convert the JSON structure provided below into the desired output format? I would greatly appreciate your guidance or a sample transformation specification that achieves this conversion. Thank you! From JSON :

[
  {
    "doc_GUID": "ae5deb48-9807-11ef-aaeb-ec2a723f4399",
    "items": [
      {
        "item_id": "00-00002475",
        "type_of_goods": "RR"
      },
      {
        "item_id": "00-00001243",
        "type_of_goods": "TT"
      },
      {
        "item_id": "00-00002997",
        "type_of_goods": "AA"
      }
    ]
  },
  {
    "doc_GUID": "e83f9131-a034-11ef-aaeb-ec2a723f4399",
    "items": [
      {
        "item_id": "00-00002828",
        "type_of_goods": "YY"
      },
      {
        "item_id": "00-000029971",
        "type_of_goods": "EE"
      }
    ]
  }
]

To this result:

[
  {
    "doc_GUID": "ae5deb48-9807-11ef-aaeb-ec2a723f4399",
    "item_id": "00-00002475",
    "type_of_goods": "RR"
  },
  {
    "doc_GUID": "ae5deb48-9807-11ef-aaeb-ec2a723f4399",
    "item_id": "00-00001243",
    "type_of_goods": "TT"
  },
  {
    "doc_GUID": "ae5deb48-9807-11ef-aaeb-ec2a723f4399",
    "item_id": "00-00002997",
    "type_of_goods": "AA"
  },
  {
    "doc_GUID": "e83f9131-a034-11ef-aaeb-ec2a723f4399",
    "item_id": "00-00002828",
    "type_of_goods": "YY"
  },
  {
    "doc_GUID": "e83f9131-a034-11ef-aaeb-ec2a723f4399",
    "item_id": "00-000029971",
    "type_of_goods": "EE"
  }
]

You can loop within the objects of the items array while bringing the doc_GUID attribute from two upper level such as :

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "items": {
          "*": {
            "@2,doc_GUID": "&3_&1.doc_GUID",
            "*": "&3_&1.&"
          }
        }
      }
    }
  },
  { //get rid of the object keys
    "operation": "shift",
    "spec": {
      "*": "[]"
    }
  }
]
