The Groovitron from Ratchet and Clank. It interacts with every enemy and boss, is pretty powerful under the right conditions, and is the right kind of silly.
Based on some reports in Bugzilla, the missing option to open in app seems to be a few month old bug. A workaround that I've been using is to "Share" the link with the app you want. Assuming the app supports it in the first place.
It's maintained on GitHub, so you might be able to manually install it or find a package for it in your package manager. At least on Arch you can install gnome-shell-extension-ddterm-git from the AUR.
I found the article and the comment, if you're curious:
