Hiding commands using JSON Format doesn't work in web part

I have a document library that I would like to show in the home page of a modern SharePoint site. I added the document library web part to the page, selected the folder I want to show, and selected the view I want to use. In this view I used JSON to hide and move around some of the commands from the command bar:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "commandBarProps": {
    "commands": [
      {
        "key": "new",
        "hide": false
      },
      {
        "key": "sync",
        "hide": true
      },
      {
        "key": "editInGridView",
        "hide": true
      },
      {
        "key": "download",
        "hide": true
      },
      {
        "key": "automate",
        "sectionType": "Overflow",
        "position": 3
      },
      {
        "key": "manageAlert",
        "sectionType": "Overflow",
        "position": 1,
        "iconName": "AlertSettings",
        "text": "Edit and Manage Alerts"
      },
      {
        "key": "alertMe",
        "sectionType": "Overflow",
        "position": 2,
        "iconName": "WorkItemAlert"
      },
      {
        "key": "export",
        "sectionType": "Overflow",
        "position": 5,
        "iconName": "ExcelDocument"
      },
      {
        "key": "integrate",
        "sectionType": "Overflow",
        "position": 4
      },
      {
        "key": "share",
        "position": 6,
        "sectionType": "Overflow",
        "title": "Share this List"
      }
    ]
  }
}

It works perfectly when I'm in the library itself:

But it doesn't when I add this library to a page as a web part:

Is it possible to modify which commands to show/hide from a document library when it is a web part in a page?
