Custom fields in the Contact form pop up dont show

Hi,

I added to the Ticket Fields 2 new fields with permission of end-user visible. I also see them in the Ticket Forms screen.
I see the new fields in the screen of ...zendesk.com/agent/tickets/new/1 , but not in my standalone website.
In my standalone website, I add the script of Zendsk to get the help button. also, I added in the script:

window.zESettings = {
  webWidget: {
    contactForm: {
      fields: [
        { id: 'name', prefill: { '*': 'name test' } },
        { id: 'email', prefill: { '*': 'test@test.com' } },
        { id: 360021007958, prefill: { '*': 'new field 1' } },
        { id: 360021007978, prefill: { '*': 'new field 2' } }
      ]
    }
  }
};

The prefill works for the name and email fields, but I don't see the new 2 fields at all. the form has only the default fields.
