First things first, I am NOT trying to clickjack - I don't even honestly know what that is or how someone would benefit from it - my question is being asked specifically for UI/UX purposes. So one thing my team loves about building sales flows with Facebook Messenger bots is that the native browser in the Messenger app functions a lot like an iframe - it opens webpages in a modal-style box with an X to close it and functions like a modal window. My question is: Is there a method in Chrome Mobile and/or Safari Mobile that allows you to do something like this with distinctly non-iframeable site pages that is NOT just opening the page in a new tab? Our goal is to open webpages in a way that they can easily be closed when the user is done with them, which will return them to the underlying page - new tabs just doesn't fit the bill. Unfortunately iframing into a modal won't work for us, although we'd love it to, because the offers we're seeking to open are not iframeable. Let me know your thoughts, I'm open to any approach and discussing, thanks!
