Magnific Popup gallery - how to add your own button to the popup window?

Question

JavaScript

There is a magnific Popup image gallery - everything is ok, scroll through and look ...

$('.image-popup').magnificPopup({
  type: 'image',
  gallery: {
     enabled: true
  }
})

It is necessary to add the "use this image" button to the popup form (with the possibility of further styling)
so that, when pressed, its own function is called, for example, displaying the name of the image file in the console.

How to implement?!
