In shopify store has one app which is Shopify Flow there was using fullscreen when the user creating any flow then fullscreen appears you can see below image and video link which i have share here

Also, I can see there is an option in app-bridge but not able to do it, there is showing a permission error so could you please let me permission how to get permission for it, because I have so much data on the page.
