Shopify Header Video Adding

I have a Shopify store, which currently has a banner image at the top of the homepage with a text overlay and two clickable links. I want to replace the image with a video I have created, full width, with the text and two clickable links overlaying it. The image of the current banner is attached. I have looked in the Shopify settings, but I only seem to be able to add images here, not a video.

Sure it's a quick job looking at Google for someone with the right know-how - Found this on the help forum. (https://community.shopify.com/c/shopify-discussions/how-can-i-incorporate-a-full-width-video-background/m-p/2521618)

Video is created; just need it adding and the overlay with text and two clickable links

Please send an example of a site you have done this to before so I can pick someone with proven ability.
