How can we upload a video and embed it into an article?

It is possible for images but this only supports image files.

And don't say it has to be uploaded to YouTube, Vimeo or DailyMotion in order to embed it.

We're trying to create company documentation and have video guides and walkthroughs which we need to embed into our docs but I can't find any way of doing this in Zoho Learn (which seems crazy).
