display an iframe on shopify app settings

I have a website that helps to create a story like we have on instagram, the user can log in to my website and manage the images, videos, stories and output.

my shopify app will create a snippet with html code and js that will pull the designed story of the user, is it possible to add an iframe of my website into the shopify app settings instead telling people to go to my site and design everything there?

this will help to achieve nice flow without going to external website.
