Video on separate tab

Hi

1)
When I import a product and this includes a video I want the video to be part of the pictures gallery in original product URL, for example this:

https://www.aliexpress.com/item/1005006393856223.html

I have tried different settings on Product video section but it seems that the only way for the video to appear is in a video tab, not part of the pics gallery. How do I make the video part of the pics gallery?

2) How do I change the color of the Shipping Method Popup window (Please see screenshot)

3) Sometimes there is a pop up window asking for email address to be able to add a product to the cart (See screenshot). How do I disable it?
