The Create Trello card action is missing a prop for urlSource. You would use this If youre adding an attachment to a trello card that is just a url, not an image. When i tried to pass a normal url thorugh the file path or url prop, it just tried to attach that path and download that link rather than go to the url.

Is there a specific app this action is for?

Need to add the urlSource prop for attaching links that are not media/images. Right now there's a field for url but its file url and not link url.
