How do I interact with a widget component in my Blueprint?

I added a health bar but I cannot seem to be able to get a reference to access the custom events inside the widget component. I can’t cast to the specific class either. So how do I get the right reference?

This, right?

custom events inside the widget
component

It is absolutely possible to override the widget component itself and add logic there. Do tell whether you mean this or the regular widget the component holds onto.
