Ok. So, I've built this out to the best of my ability.

When I add "additional comments" I get the notification and it looks good.

When I add work notes, I'm not seeing anything but the additional comments.

I'm going to guess that my work notes condition is null because end users can't see these normally and this notification would go out to them as well? So, is it possible to have it both ways?

Here's the condition builder I created.
