Set the Policy-Permissions in the header via Zoid

[0x4Graham]

Is it possible to set Policy-Permissions in the request via zoid?

I have an issue where I require the iframe to make use of USB. I added the following but it's not working:

• on the iFrame it's loading allow: usb, but still getting the following error: Permissions policy violation: usb is not allowed in this document.

      attributes: {
        iframe: {
          allow: 'usb',
        },
      },
