How can I set the color of the DualShock 4's lightbar on PC?

Hey there, I’ve searched around for documentation on how to set the DualShock 4’s lightbar color by code for a PC game and can’t find anything. Unity says it already has full support of the DS4’s features for PS4 development, but I can’t even find documentation about that either.

Is it possible to access and interact with the lightbar on PC or am I just out of luck?

Unity has full support for the PS4 including its controller IF you have a PS4 Unity license. To get that you first need to be an official PS4 developer. Even then the controller most likely will still only work when connected to the PS4 as there are no official PS4 Controller drivers for pc.
