How To Take Screenshot With PS3 Controller worked with SCPToolKit?

[Dudeless]

Hi,
I have a DualShock 3 controller and I installed SCPToolKit in order to be able to play my games using it. But because I couldn't make it work with the newest version of it, I installed a BETA version and it is making it look like I plugged in a XBOX controller.
I want to take screenshots using my controller but I wasn't able to find how.
I tried to look it up at the "Steam Button Chord configuration" settings in Big Picture Mode but it says that it only works when I hold the Steam Button and because that my controller is not a Steam Controller, I don't have such button.
I tried using PS Button but I'm not sure if it works.
When I'm in a game and press the PS Button, a weird lighty-thing appears on the screen. And when I try to press R1(which is the default screenshot button i think) on my controller while the screen is lighted, nothing happens. No notification, no sound. I even tried to quit the game and check the screenshot folder but still nothing.

Here is the screenshot of the "Steam Button Chord configuration" screen in Big Picture Mode. It may help you see what I'm doing wrong.
