How it works “messages from parent ”& “messages from component” ?

I’ve searched the [Docs] , but I still can’t understand this.
Can someone record a video program for that?
Thanks!

The same things. The documentation does not help. I’m trying to play with that. I tried different options for different cases but nothing works. It looks like it’s buggy.
