Hide top header in embeded video

Hello Alvin, 

Customization of this nature would require using our UI element instead of a WebApp generated embed widget. 

You can find more info: https://developer.box.com/guides/embed/ui-elements/preview/

Here's an example on a content preview: https://codepen.io/box-platform/pen/OeavRB

The UI preview docs is really confusing. It says here that `The content Content Preview element is currently not available via NPM.` Im trying to achieve this is react how else can I do it. I do see a demo for content preview but looks like there is a lot of setup required for that. i wish there was a tutorial or proper docs to setup content preview and use in something like npm

I was following this but some dependency doesnt match and it throws an error saying not valid import in the box-ui-elements module which I dont know how to resolve
