Azure DevOps extension custom hub group and hub under Organization Settings

I want to add a custom hub group and hub under Organization Settings.

Currently, I am doing this but the menu is under the Extensions hub group.

How can I customize that one so that I will have a custom hub group:

{
   "contributions": [
    {
        "id": "collection-level-admin-hub",
        "type": "ms.vss-web.hub",
        "description": "Description",
        "targets": [
            "ms.vss-web.collection-admin-hub-group"
        ],
        "properties": {
            "name": "My Menu",
            "order": 100,
            "uri": "dist/index.html"
        }
    }
  ]
}
