Ok, so i have found this location in the map editor Json file using NotePad++ to open it.
"OverrideShooterGameModeDefaultGameIni":
So if i wanted to add the script from the first link i referenced, do i need to add the quotes before and after each line as shown here?

Or, can i just use it as is as represented here?
