How to make an attachment with VK reviews on the site?

Question

HTML

The fact is that I need to make a page on the site completely with reviews that are already in the discussion, and the ability to leave comments. I tried to use the widget from Vkontakte, it's a bit different, there is no synchronization (bundle) of the Vkontakte discussion itself and the tab on the page.
When I tried to do this, it turned out just this:
I need something like this, only as a separate container on the page (just as part of a site - I didn’t find it, but there definitely are, I saw it earlier)
How to implement this? I would be very grateful, because there is no information on this subject anywhere on the Internet.

https://disqus.com doesn't work either?
Nesting, pictures, gifs, videos, everything is there.
