You can use my mod Dylbills Papyrus Functions which includes DbSkseEvents. https://www.nexusmods.com/skyrimspecialedition/mods/65410
Example, assuming your script is attached to a form.
Event OnInit()
DbSkseEvents.RegisterFormForGlobalEvent("OnItemCraftedGlobal", self)
EndEvent
;must re register on load game
Event OnLoadGameGlobal()
DbSkseEvents.RegisterFormForGlobalEvent("OnItemCraftedGlobal", self)
EndEvent
Event OnItemCraftedGlobal(Form itemCrafted, ObjectReference benchRef, int count, int workBenchType, string benchSkill)
if benchSkill == "enchanting"
Debug.MessageBox(itemCrafted.GetName() + " enchanted")
Endif
EndEvent
