Trouble autoplaying video from button link

Site URL: https://www.patrickkaplin.com/

Hello,

I'm having a simple design problem that I can't seem to figure out. I'd like the following video to autoplay once the "Play" button is clicked from the banner on the home page. (https://vimeo.com/manage/videos/293786211)

Any help would be greatly appreciated.

Thanks so much,

Anybody have any leads?
