... where do I get this extension?
There's a link to the latest validated version: top right of the screen
and at the bottom there's REVISIONS (to the right of SCREENSHOTS) containing links to available versions (including non-validated ones).
Added:
if you're going to use various extensions and perhaps modify some things (even if it's only style related), I strongly suggest you invest some time in a personal webserver (and I suggest/recommend the most basic one to start with: USBwebserver, use version 8.6.6 with php 8.0.7) so that you can test everything on your PC. If you online board runs with php 7.4 then use USBwebserver 8.6.5.
Once you get the hang of it, use a more complete package (e.g. Wamp, Easyphp, XAMPP)
added again: the above assuming you're using Windows.
