Can anyone tell me what plugin this site is using?

I’ve been trying to find this social plugin for a while now, seen it bein used on multiple sites. I believe I used all the methods out there to try and find out what plugin it is without any luck.

Its a social plugin, popup overlay box that displays a facebook share button on first step, then on the second step it displays a facebook like button; with the possibility to close the pop up overlay. It seems the plugin has the same layout, css so it must be something I can find in the plugins section here or purchase it from a marketplace.

The plugin can be seen here for example. It will just pop up instantly once you land on the page.

This is one example screenshot, the layout of the pop up is a little bit twisted. https://prntscr.com/5clhox

If anybody can tell me what plugin this is I would be greatful. Thanks in advance.
