Make Modal capture figcaption

问题

so I have this code for a fig caption and a modal to show up on mobile and tablets, but I would like to make the modal open my caption instead of writing the caption again inside the modal.

I have many images with captions, so this with be optimal

How is this possible?

Thanks
