Add image to OneSignal push notification via REST API

How can I add an image to an iOS push notification? I tried setting the imageUrl property, but it did not work. However, I was able to make it work by using the UI from their website.

{
      app_id: process.env.ONE_SIGNAL_ID,
      include_external_user_ids: d.emails,
      headings: { en: d.headings },
      subtitle: { en: d.subtitle },
      contents: { en: d.contents },
      app_url: "https://google.com",
      web_url: "https://google.com",
      ios_badgeType: "Increase",
      image_url:
        "https://cdn.pixabay.com/photo/2018/01/21/01/46/architecture-3095716_960_720.jpg"
    },

The correct property to add an image to an iOS push notification using the OneSignal API is big_picture. Here is how the code should look like:

{
      app_id: process.env.ONE_SIGNAL_ID,
      include_external_user_ids: d.emails,
      headings: { en: d.headings },
      subtitle: { en: d.subtitle },
      contents: { en: d.contents },
      app_url: "https://google.com",
      web_url: "https://google.com",
      ios_badgeType: "Increase",
      big_picture:
        "https://cdn.pixabay.com/photo/2018/01/21/01/46/architecture-3095716_960_720.jpg"
    },
