Need help finding a (free) plugin for a student project.

Firstly, I got FCPX yesterday so I may ask beginner questions.
Secondly, the rules tab is empty, so please let me know if i'm posting this in the wrong place, or other etiquette that I need to follow.

Finally:
I'm working on a video demonstration of a product. I have the product spinning and stopping and would like to add facts about it to the video.
What we want is something that is similar to the standard title element: Card. We would like to have a smaller text box and some kind of arrow or mark that point to the point of interest on the product.
Do you know of any plugins that does this in a visually good style hopefully for free?
Or, do these kinds of overlays have a typical name that I should google?

Edit: I have tried looking around this forum for it, but have so far been unable to find it.

Thanks in advance.
