please remove the top/side pop downs for PDF viewing

when I use brave browser to read PDF files moving the mouse to the bottom right side or up top will cause the browser to display a pop down from the top with file info & a few buttons, and a +/-/ full screen to appear at bottom right side

THIS FEATURE IS TOTALLY GDAMN ANNOYING PLEASE FIX IT TO STOP THESE AUTOMATIC POPUPS/POPDOWNS WHATEVER TF THEY ARE CALLED

there has to be a better way to implement this needed functionality

I spend hours reading PDF files and instead of installing FOXIT or some other pdf reader I’d like to keep using this brave browser but liklely I will just trash this thing because this 1 feature is so annoying - how can people use this crap ? I spend like 20% time clearning these gdamn popups trying to read files

current browser version is -
[Version 1.2.42 Chromium: 79.0.3945.117 (Official Build) (64-bit)]
