Yandex Map icons on wordpress?

You want to insert a map on a website with icons.

Examples:
webmap-blog.ru/bez-rubriki/dobavlyaem-metku-na-kar...
https://tech.yandex.ru/maps/jsbox/2.1/plcemark

The problem is that I do not know how to put this exactly in my case. In the screenshot you can see the field where I can insert. I tried already, nothing happens. Don't quite understand the error.

What can I do?

I saw that such a plugin https://ru.wordpress.org/plugins/yamaps/, but I have not quite an ordinary field where to insert the code with this plugin. Don't know if it will work.

Previously used this code, it works, but I need icons.
