I have a rosbag that has one topic of type CompressedImage. I would like to visualize that in rviz.

How can I do that?

(right now, in rviz I can visualize Image topics)

For your reference, I found that post by using Google, using rviz compressed image site:answers.ros.org as the search query.

The solution in the linked question seems good. However it is incomplete as it does not explain how to select "compressed" from the list when it does not appear

Either there are no compressed images published, the correct topic structure is not present, or you don't have the image_transport_plugins installed.
