Adding web (iFrame or so on) to slide from Add-ins that extend functionality
Lot of Add-ins developers wants to create extend Add-in with adding same content to slides functionality(more, than images or text, that is allowed by setSelectedDataAsync method).
So they have to use Content Add-inns, and user have to add them to slides several times (for examle vote widgets of Mentimeter app.)
Its very unconvinient!
Please provide us extended the functionality of adding web pages to slides
