When adding a video block to 7.1, does anyone know if you can remove the PLAY button and have the video just autoplay?

I know how to do this for background art but not sure if the code will work on video blocks. You can try it through.

/*hide play button*/
.background-pause-button.visible {display: none!important}

For people without disabilities, autoplay media is an annoyance, but for people with some disabilities, autoplay can make a site unusable. Some of the possible unintended effects: 

People with cognitive disabilities may find media confusing or distracting.

Media may trigger seizures and other physical reactions.

Autoplay media can prevent users from navigating a site in a natural, intuitive way.

Autoplay can prevent users from hearing or otherwise conflict with screen readers, frustrating users who utilize text-to-speech software.
