How to access private mode without access to screen? Galaxy S5

[AC Question]

So, I'm an ***** and was working too close to my phone with some heavy tools. Long story short, I ended up dropping my Dewalt drill directly on the screen. It's completely ruined and no longer has any picture on the screen. The phone itself still turns on. I'm able to unlock with fingerprint, etc. The problem is...since I can't actually see anything on the screen, I'm not sure exactly where to press and swipe to access private mode. I had some files for work stored in private mode that I need to retrieve from the phone (customer contracts)...but since I can't see anything, I don't know exactly how to get them back. Any ideas? Thanks in advance!
