Extension not appearing


I installed face centroid to try and find the centroid of some odd shapes I’m creating. My sketchup says its downloaded, and I activated it in preferences, but when I right click on my shape the option shown in the tutorial stating the extension should show up does not appear. Am I missing something?

My guess is you’re right clicking on a group.
Try double clicking on the group to enter its editing context; then right click on the face.
