BJ Lazy Load 'background-image' images?

Hello,
Can someone give me an example on how to enable lazy load for background-image?

This is the code I want to lazy load
‘<div class=”latest-article-images” style=”background-image: url(‘<?php the_post_thumbnail_url(‘medium’); ?>’)” itemprop=”image” itemscope itemtype=”https://schema.org/ImageObject”></div>&#8217;

Thanks you,
