Is it possible to randomly put matinee animation at different locations when animation has finished playing?

I added an event in the Event track of the empty group. In the level blueprint, I connected the matinee controller with the label, “Finished”, to a Print String node. This is so that I can tell the event has actually fired.

After I added the matinee controller, do I need to do something so that it can trigger the event?

I don’t see an obvious way to trigger the event. Even if I added in selected actors after the matinee controller is placed in the level blueprint, and the selected actors finished their animations, the event doesn’t trigger at all.
