I am trying to create a project type that displays an iframe. I see kirby has the Html::iframe class, but I do not understand how I am supposed to use it. I set up my project.canva.yml to have an url field, so I am hoping to put that url in an iframe when the project page loads.
Also, is there a way to get a thumbnail of the iframe to be stored/displayed on my website that is similar to how the projects page shows the cover image of each project?
Thank you for your time.
