Can’t get Video Markup to show

Hi, I’ve just added the settings for video mark up as described here https://schema.press/docs/videoobject-markup/
But no markup shows in the page. The test tool doesn’t show any errors, but equally it doesn’t show the mark up (the other mark up is showing).
If it helps, I’m using fusion builder in Avada Theme.
Can you advise please?

Thanks

Anni
