Scrolling bars when adding a Rise course as a Web Object in Storyline 360

I am using Rise to build a scenario and trying to add it into Storyline as a web object. When I publish to Review to look at it, a scroll bar appears and it behaves very poorly from a user perspective. I have tried making my web object larger, but even if it is full screen the scrolling is still required.

I can't seem to find where I can adjust the published Rise screen size.  These are the instructions I am following (https://community.articulate.com/series/articulate-storyline-360/articles/storyline-360-adding-web-objects) and I have the web object set to display in slide. How can I make this user experience better?
