This should work. I tested it with a list size of one and was able to see the icon property value. I just don’t have a longer JSON response to test it with.
You’ll need to supply your own API url. If it doesn’t work, please supply the API url you are using as text (not a screenshot), removing the API key if you prefer. Please also copy the JSON response from the text input and paste it into a post here as text (it’s best to use the “Preformatted text” icon in the forum toolbar when doing this).
