Yes, that's true. The PDF viewer has to support popups. I normally use zathura to view PDF documents but that's one example of a viewer that doesn't work with this document. In cases like this, I switch to evince (others also work). But I find this document very useful. -- : Eric S Fraga, with org release_9.6-124-g036cc0 in Emacs 30.0.50
