Detect specific MagicEffects on ReferenceAlias

[blabla11]

I'm trying to detect if anyone/thing has cast a Fear spell on an NPC held in a ReferenceAlias.
I know I can use Event ObjectReference.OnMagicEffectApply(ObjectReference akCaster, MagicEffect akEffect), but the API on MagicEffect Script has me stumped as to how exactly I can extract the information I need from it, specifically if the Effect Archetype is Demoralize.

 

I'd like to not check ActorValue(Confidence) since that might kick in without an actual spell.
