Thanks for link to the video, alison. Unfortunately it didn't help. Since it's 480p I can't read anything on the presenter's screen. I know I didn't follow the steps correctly, but since I can't actually see what he did I don't know where I went wrong.
This issue has been kicking around for two years and still hasn't been adequately addressed. It's really important, since without good instructions people can't actually use the module. If this were a big in the source code, it would be the kind that prevents the module from working at all.
I'd love to contribute documentation--I'm good at writing it--but since I don't understand how to use the module myself, I can't write it. Is there anyone who has got this working who's willing to walk me through it via Zoom or something? Then I could contribute better documentation.
