Expand to full screen view when shared through SharePoint

When we share the report through (open) web, end user open the url, the report comes very much full screen, nice utilization of real-estate. But web sharing is not secured! Now, when sharing through SharePoint, it embades the report into Power BI web part and comes up with lot of white spaces and unnecessary scrolling. If we can get a function within the Web part to "Enter Full Screen Mode", it will be very helpful from user experience perspective.
