Html image swap on click for COA

Hey team, I just saw what Yungwknd and IphaCentauriKid did with the COA and was wondering if there were any instructions on building an extension like this.

On the claim page, if you click, it swaps out an image to show the COA, which is brilliant.

I do a fair amount of physical + digital and use NFC chips for that pairing. I love this solution you have with the COA. I’m not sure if there is a way to showcase three images (digital + physical photo + COa, but that would be epic). Would love to talk shop

Here is the link: The Muse - Cosmos

Anyone creating this extension or have documentation? I’d love to use this asap.
