How to place YAN blocks in a Zen article?

Question

contextual advertising

Good afternoon. I came across this article https://zen.yandex.ru/media/id/6001a44863122536bbc... by default, Zen places only 2 ad units, as you can see there are more of them, therefore they are placed manually. Maybe someone knows how it is implemented

Answer 1

I'm not talking about the technical part. But there are not only YAN blocks, these are other advertising networks.
