Merge / Combine object arrays into single object

I have an object with key values, and those keys each contain an array of objects:

var obj = {
  "0": [
    {
      "category": "A",
      "index": 0,
      "property": "Name",
      "value": "Bob"
    },
    {
      "category": "A",
      "index": 0,
      "property": "Surname",
      "value": "Dylan"
    }
  ],
  "1": [
    {
      "category": "A",
      "index": 1,
      "property": "Name",
      "value": "Elvis"
    },
    {
      "category": "A",
      "index": 1,
      "property": "Surname",
      "value": "Presley"
    }
  ]
}

How would I go about merging the objects into one single array with the objects combined therein? The objective is to have the result return the following:

var obj2 = [
        {
          "category": "A",
          "index": 0,
          "property": "Name",
          "value": "Bob"
        },
        {
          "category": "A",
          "index": 0,
          "property": "Surname",
          "value": "Dylan"
        },
        {
          "category": "A",
          "index": 1,
          "property": "Name",
          "value": "Elvis"
        },
        {
          "category": "A",
          "index": 1,
          "property": "Surname",
          "value": "Presley"
        }
    ]

I've tried to make use of LoDash union and join, however to no avail.

Assuming your example was wrong, and it's actually like below (since what you put in isn't even valid), you can just use Object.values(obj).flat()

var obj = {
    "0": [{
      "category": "A",
      "index": 0,
      "property": "Name",
      "value": "Bob"
    }],
    "1": [{
      "category": "A",
      "index": 1,
      "property": "Name",
      "value": "Jessica"
    }]
}

console.log(Object.values(obj).flat())
