When creating Umbraco.BlockList with Items programmatically they are not showing, how to 'publish' them?

When I create a blocklist with this as the Umb.PropertyEditorUi.BlockList with that has this in the database for table

umbracoDataType: {"blocks":[{"contentElementTypeKey":"d0eeca25-ed03-4282-af88-eebfd2a003f6","label":"{umbValue: eventItemTitle}"}]}

I create it as this, the same as if i create it from the backend only the “key” and matching “contentKey” values are generated by me:

{
  "contentData": [
    {
      "contentTypeKey": "d0eeca25-ed03-4282-af88-eebfd2a003f6",
      "udi": null,
      "key": "cd58fb64-091f-4dbf-ba61-6d028fd580a3",
      "values": [
        {
          "editorAlias": "Umbraco.TextBox",
          "culture": null,
          "segment": null,
          "alias": "eventItemTitle",
          "value": "test"
        }
      ]
    },
    {
      "contentTypeKey": "d0eeca25-ed03-4282-af88-eebfd2a003f6",
      "udi": null,
      "key": "d2f4cfa5-6b44-42dd-bca9-d17cef767526",
      "values": [
        {
          "editorAlias": "Umbraco.TextBox",
          "culture": null,
          "segment": null,
          "alias": "eventItemTitle",
          "value": "test2"
        }
      ]
    }
  ],
  "settingsData": [],
  "expose": [
    {
      "contentKey": "cd58fb64-091f-4dbf-ba61-6d028fd580a3",
      "culture": null,
      "segment": null
    },
    {
      "contentKey": "d2f4cfa5-6b44-42dd-bca9-d17cef767526",
      "culture": null,
      "segment": null
    }
  ],
  "Layout": {
    "Umbraco.BlockList": [
      {
        "contentUdi": null,
        "settingsUdi": null,
        "contentKey": "cd58fb64-091f-4dbf-ba61-6d028fd580a3",
        "settingsKey": null
      },
      {
        "contentUdi": null,
        "settingsUdi": null,
        "contentKey": "d2f4cfa5-6b44-42dd-bca9-d17cef767526",
        "settingsKey": null
      }
    ]
  }
}

When I change 1 key by a key that is created in the backend, I get the 2 showing but 1 shows ‘in Draft’.
Do I need to do something to create those keys? Currently I just create them with a new Guid.

Hopefully someone can give me a quick answer because I don’t see it. Thanks in advance!
