Hello, I've read that this issue was closed due to low request. We are working with Confluence, Moodle and [H5P|https://h5p.org/] as our pedagogical tools and we'd love to get the great interactive content created with H5P embedded into Confluence. A lot of universities and places are using the tool more and more. 

Embedding the content is also not possible with the Widget Connector macro nor with the iFrame, so an alternative would be to have a macro that allows to embed an HTML5 embedding code, like the one from the Wordpress editor, for example.

Are you considering some of the above?

Thanks!
