End user launcher with Graphics settings

I’m are on 4.11, and I try to make an own launcher with scalability settings, but I’m stuck

I want the end user to be able to choose resolution, some graphics quality settings and VR mode.

Scalability grups works fine when i use in BP/widgets, but is not an elegant solution for VR,
and works too when i change settings via GameUserSettings.ini in “MyGame\Saved\Config\WindowsNoEditor” on Development package, or via GameUserSettings.ini in “\AppData\Local\MyGame\Saved\Config\WindowsNoEditor”
on Shipping configuration, but AppData folder is a hidden folder…

I try to create an .ini file called DefaultGameUserSettings.ini and place it in the MyGameProject\Config,
but this file does not carry over to my shipping packaging output, and copy it on “MyGame\Config” doesn’t work

What is the way forward for change those settings with the launcher on a shipping packaging?
