I am currently using H5P on Drupal 8 and would like to try the h5p-three-image library. Although it seems that Drupal 8 H5P doesn't have a developer mode so the only option is to upload files manually in .h5p format. This would be fine but the package that is available on github is not in this format, so I have tried to package it using the h5p cli but no matter what I do I get the error "You must specify the libraries". Is there any other way to get this working in Drupal? Or am I missing something for the cli?
Any suggestions would be greatly appreciated.

Thanks in advance,
