How to embed your app in a webpage without iFrame or Embed code... easily

There was a way to do this with a formula that @tim.young posted a while back and I can’t find it now. I’d like to use it now. Does anyone have a link to that forum post?

Edit: Found it…How can I embed my 360 tour on a page? - #9 by Rez
