Where do i find the file for changing the button above restart option

[X-netrunner]

Okay so I had to reinstall my arch , i previously made a swapfile for hibernation and enabled it , at that point the button above the restart option aka hibernation button worked.
But in my new install I just wanted to use suspend instead of hibernation. And i can not find the file to edit the option from hibernation to suspend
i have tried searching for SessionConfig.qml but there were no matches on my system
