navigation bar and embedded PowerPoint

Hi,

I was hoping that I could turn off the grey navigation bar at the bottom of embedded PowerPoints online. Our team wants to control navigation through hyperlinks only, in order to create multipath presentations for training. Is there a switch similar to  (frameborder="0") or (frameborder="1") that can do this? e.g. (navigation="0") or (navigation="false"). This will be very helpful for creating eLearning  and eGames.

Thanks

Luke
