Add call-to-action overlays to YouTube ads

A call-to-action (CTA) overlay is an interactive element that appears over an ad and can help drive clicks to your website. An overlay appears when the video starts, and collapses into a thumbnail image after 15 seconds. On desktop browsers, the CTA expands when viewers hover over it. On mobile browsers, the CTA expands when viewers tap the thumbnail image.
