Spawn an actor when it's leaving a trigger (the same actor)

Hello everyone,

It’s my first post here and I think you’re gonna see me quite often !

Actor is a Blueprintclass for the VR starter kit map.

I’m trying to spawn an actor ‘enfant1’ when this actor leaver the trigger ‘triggerventre’.
It doesn’t work and I don’t find a tutorial I can follow.

Can you explain me why please ?

Nice evening,
