Particle System not showing on my default pawn

Hello there, I downloaded an asset with several visual effects, they all come in blueprints.
I tried to mimic the blueprint and could create my own blueprint with the same particle system of another blueprint that came originally from the asset.
However when I add a Particle System Component to child of my DefaultPawn_BP , it no longer shows up, and I can’t understand what I am missing.

Any thoughts?
