Host Articulate storyline on Sharepoint 365

Hi, 

I have followed many of the channels on how to publish/host articulate storyline on Sharepoint by transforming the html file into aspx and then deleting the html file, however, I haven't succeed.. Simply, I am prompted with a request to download the file, and still when clicking 'open' nothing happens. 

I actually just need to host my articulate storyline and then be able to link to it, so that everyone can access it. 

Any good advice that will work for online sharepoint 365?
