Enable lazy load for Facebook like button

Hi.

I have tried all the different lazy load Facebook like button plugin for Wordpress, but none of them work correctly for my multisite. I finally found a plugin that works here: https://wordpress.org/plugins/facebook-button-plugin/ but it is not lazy load. Is it possible to modify the plugin, so it will lazy load on my site, like the images? And again, please notice that I already have tried the lazy load buttons for Wordpress.

Thanks!
