I can't find config files in games I got with Xbox Beta

[Rafael]

I can't find settings files in games I got with Xbox Beta. I tried following the paths posted here and even seaching by the file names. It seems that these files are encrypted or hiden in some diferent place. It happens only with games I got in Xbox beta service. Unfortantly, set mouse sensitivity in-game sometimes is to much inacurate.

EDIT: I guess this is like games though Microsoft Store, you have absolutely no access to the game files. Unless the config file is located in a location like "My Documents" or %LOCALAPPDATA%, there is no way to feasibly access them.
