How to Export PopcornFX to World Editor?

Blizzard, how do I export PopcornFX with “pkfx” particle files to World Editor properly? Looks like the Reforged particles are created from PopcornFX. And, I am trying to make some of my own particles with PopcornFX, but how do I export it to World Editor from PopcornFX? Thanks. :slight_smile:
