How to manipulate classes in Yandex map?

Question

JavaScript

Hello!
I'm trying to manipulate classes on the Yandex map.
I tried both through js and through css and nothing. Maybe I'm not doing it right, tell me what is the reason?
For example js:

var remmapblock = $(".ymaps-2-1-65-islets_card__row-links").click(function(){
      remmapblock.addClass('qaz');
    });

Answer 1

$( this ).addClass('qaz');
