We want to add new content into the nintex mobile app (App studio) but we want each content to be only viewable to a specifi list of users. They are basically PDF's. 

We are thinking to add a "Resources" tab. and each content will be a separate PDF. Our app hosts many forms that are permission trimmed on SharePoint, but we want to add the tutorials and trim them per a permission group or a distribution list. Is that possible? 

I don't see a way to do that in App studio, but can we use the HTML page option and purpose it to do that? and how!
