Inside of animation blueprint transition details, where are these events called too/how can I use them to call an event?

[Killerbanaple]

I want to call an event when my player characters transition from idle to aiming (or walking to aiming) is completed so that I can add an overlay image to give additional details for aimed attacks. I see that there are three spaces where I can create event names but am having trouble figuring out how to access/call these from anywhere. Does anyone know how to do this, or a better way to initiate events on completion of an animation blueprint transition?

When you enter txt in the notify event field, it will let you create an anim notify event in the event graph. Like so:

Added a notification start transition called jumpify

Then in event graph I can add matching event

Only played a sound to test it, but other logic can run there.
