Background and Popup Video

Hi team,

I want to embed a video in my GeneratePress site in such a way that:

The video autoplays (muted) when the page loads.

If the user wants, they can click on it to watch with sound (like expanding into normal play mode).

Here’s a reference example of what what i want https://share.zight.com/eDuDblmX

Could you please guide me on the best way to achieve this in GeneratePress + GenerateBlocks?
– Should I use the core video block or a custom HTML embed with autoplay, muted, and playsinline attributes?
– And how can I allow the user to click to enable sound/play without breaking autoplay?

Any code snippet or recommended approach would be really helpful.

Thanks!
