I am trying to create a custom domain name (already acquired) for an MS Sway site of the form sway.com/<id here>. The domain service provider uses a dummy page with iframe to display the contents of the actual page as well as to show a ghost domain name in the address bar. It seems sway.com server used to allow this but now is setting X-Frame-Options to SAMEORIGIN and hence the iframe displays nothing. Has anyone succeeded in doing this or any other way to display a custom domain name for a Sway site? 
Is it possible to use a custom domain name for a sway.com site?
