How might we use ARIA in Storyline?

I recently started experimenting with JavaScript in my courses, and came across this article about ARIA from Eric Bailey in Smashing Magazine, featured in Silktide's newsletter this afternoon. In searching the community, posts around ARIA seem to be pretty old, but it looks like there may be possibilities here. 

I am not a coder, but know enough HTML to tweak things, and how to create and leverage JavaScript thanks to AI tools. Has anyone experimented with ARIA in a course? Are there any best practices?
