How to change the site logo in the Yandex browser scoreboard?

Question

After changing the logo on the site, it did not change in the Yandex scoreboard of the browser, clearing the cache of the site and the browser did not help.
A question was asked in support of the Yandex browser, we were sent the following instructions:
