Steps to reproduce the problem:
the docs say this is how to make an image notification, but the type says basic... doesnt work unless you replace it with type: 'image'

var opt = {
  type: "basic",
  title: "Primary Title",
  message: "Primary message to display",
  iconUrl: "url_to_small_icon",
  imageUrl: "url_to_preview_image"
}

What is the expected behavior?

What went wrong?
doesnt load notifiaction

Did this work before? N/A
