Check the Browser compatibility table carefully before using this in production.
The HTTP Permissions-Policy header autoplay directive controls whether the current document is allowed to autoplay media requested through the HTMLMediaElement interface.
Specifically, where a defined policy blocks use of this feature and there were no user gestures, the Promise returned by HTMLMediaElement.play() will reject with a DOMException. The autoplay attribute on <audio> and <video> elements will be ignored.
Note: For more details on autoplay and autoplay blocking, see the article Autoplay guide for media and Web Audio APIs.
