How to turn off hud in Might & Magic Heroes VII

Sorry if the video is a little bit messy, ive never recorded something like this before

I made this video so other people dont need to search through the game files or internet forums and waste their time. I went to many Homm serwers but i didnt get any answer how to turn hud off. Then i decided that i will find this by myself and i did it, it took few hours but it was worth it.

Also if you dont have documents in start menu then go into:
