Embedding Unlisted Vimeo Video into Keynote

I am trying to embed a Vimeo video in to a keynote. The video is 'unlisted' so only available using a specific URL on Vimeo find it.

However when I try and embed the video in to my Keynote I get an error to say the URL isn't a valid Vimeo URL. The format of the url is:

https://vimeo.com/[VIDEO_ID]/[HASH]

This is a valid Vimeo URL and should be recognised as such - any ideas how I can get this to work?
