I added the animation and I don't get it running. I managed to get some other animation running on the same test site, so I am wondering is this a bug (Missing ID thing, library not clickable?) or am I doing it wrong?
PS: I am using Gutenberg as a Plugin and a theme that uses theme.json and the new 5.8 site builder, but that is dropping in just two weeks, so I assume your are testing against it.
