Hot spot knowledge check

I’m creating a module (captivate 11.5) on email phishing. I have an email sample, and I want the users to identify the clues that the email is not legitimate. I’d like the question to be graded, so I used the quiz>knowledge check>insert questions and then selected Hot Spot. Now that I’m there, I’m stumped on what to do next.

Hotspots

Can anyone help me find a resource on how to implement hotspots into a project?
