New to VFX Graph- How to make particles shoot out opposite way of objects velocity?

I have an effect I'm trying to achieve, where particles fly out the opposite way of the Game Object's move direction. How can I do this in VFX Graph? The only thing I've figured out is that I need the Set Velocity from direction and Speed (New Direction) node. I just don't know what to put into the Direction.

 

First you need to pass game object move direction to VFX.
If you don't know how to do it you should start with tutorials.

 

Oh is that the best way to do it? With a script outside of the VFX Graph? I thought there would be a way within VFX Graph. I know how to pass information into VFX Graph, I just usually save that as a last resort.
