How to get a character BP to interact with another BP?

I’m clearly misunderstanding something, trying to kill a BP now (previous trigger) but can’t find any tutorials. So I’m guessing it’s the same as destroy actor? Here I have added 2 nodes at the end of my item pickup tree. I was hoping it would go on and cast to my previous trigger (speech_a) and destroy it? Doesn’t work.

I then tried connecting from a colored node as you mention but still no luck.
