Node "Event BeginPlay" AND Node "Do N"

Hi everyone!

I am trying to make the light turn on and off a certain number of times when starting the scene. At the same time, I want to IMPLEMENT this through the "Event BeginPlay"node. I try to make the number of flashes through the node “Event Begin Play”, but the node “Event BeginPlay” in any case performs all subsequent nodes only once!

At the same time, in the “Event Tick” node, I calmly manage to implement my task.

How do I make “Event BeginPlay” run multiple times?
