I cannot hide the "New" button in SharePoint list using JSON

Question

I have tried using the following JSON code to hide the "new" button from SharePoint list but it has no effect. It works on all other buttons except new. Can some please help?

Here is the JSON:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "commandBarProps": {
    "commands": [
      {
        "key": "new",
        "hide": true
        
      },
      {
        "key": "New",
        "text": "Fred",
        "iconname": "Fred"
      },
      {
        "key": "share",
        "hide": true
      },
      {
        "key": "edit",
        "hide": true
      },
      {
        "key": "automate",
        "hide": true
      },
      {
        "key": "alertMe",
        "hide": true
      },
      {
        "key": "integrate",
        "hide": true
      },
      {
        "key": "manageAlert",
        "hide": true
      }
    ]
  }
}

I just tried using below JSON in SharePoint list view formatting and it works fine for me:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "commandBarProps": {
    "commands": [
      {
        "key": "new",
        "hide": true
      }
    ]
  }
}

Output:

Note: New button will not be hidden from all views by default. It will be hidden only from the list view where you have applied the JSON.
