How to implement the "correlate cards" task in js?

Question

JavaScript

This is how the task looks like

How can I get a card on which another card was dragged?
There is an idea to somehow get the element under the active card on the mouseup event, but I don’t know how.
Everything is written in vue and done through mousup and mousedown
