Switching 8-bit pixellize post process

I followed the tutorial and have the ability to turn on and off the 8-bit pixellize effect. What I am wanting to do is there a way using blueprints or some other way to have an event turn on for a period of time that effect, and then switch it back off. In other words, enable and disable again. Not sure where to get started with this.


Is your pixelize in a post process volume at all?
