New- Storyline into Rise 360

I am relatively new at this. We hired a contracted instructional designer to create a few Storyline courses for us. As Rise (IMO) is much simpler for the "lay" person to figure out, the plan was for me to then take those Storyline courses and import them into various pages in an overarching Rise course. 

I had the Instructional Designer share the project files with me both so that we can make updates to teh course if we ever need to and so I could import them into my own Storyline account and publish them to REview 360 to be able to share it in the Rise course (as it's my understanding that's the only way Rise can have the courses be viewed). 

It all just seems so overly complicated. I can't figure out which files to try to important, can't figure out where to do it. Was she supposed to send me a different type of file? Like maybe a .story? Any help is appreciated.
