Abcjs plugin help

I’m trying to move my collection of music research, notes, and sheet music to Obsidian. Right now the music is stored as a series of ABC files. I found the abcjs plugin through the “community plugins” page inside Obsidian. I’ve started a note with a section of ABC music as shown on the web page, yet when I switch to reader view it just renders the text and not the music score that I expect. There doesn’t seem to be a help forum on the GitHub page for the plugin and no instructions other than a couple of examples in the readme.

Is there some other step or thing I need to install to make this work? Thanks!

Obsidian 1.5.11
macOS Ventura 13.6.6 (Intel CPU)
obsidian-plugin-abcjs 1.4.0
