How to remove the right column in the popup with labels that appear when you click on a cluster?

Question

Yandex maps

On the map, if the marks are nearby, they are combined into a cluster. When you click on a cluster, you need to display a list of tags: icon + tag name .
Is it possible to insert your own code with a list of tags there? Since you also need to style it with your css.

I do not need this right column.

When you click on the desired label, you need its description to open in a new window.
