How to ban the youtube.com domain in squid, but skip sites with embedded videos?

Question

Squid

The organization uses the Squid 3.3.8 proxy server to filter a number of sites by category: social networks, video hosting, porn, games, etc. Domain lists are loaded from files using the following construction:

# Список шаблонов фильтрации видеохостингов
acl video_hostings dstdomain "/etc/squid/lists/video_hostings"

and then applied like this:

# При срабатывании фильтра video_hostings выдавать пользователю страничку с ошибкой ERR_NO_VIDEO
# Запрещаем видеохостинг
deny_info ERR_NO_VIDEO video_hostings
http_access deny video_hostings
access_log stdio:/var/log/squid/video_hostings.log common video_hostings

In the course of work, it became necessary to allow users to watch YouTube videos on the useful site example.com, but at the same time leave a ban on going to youtube.com. How to do this using squid and is it possible in principle?
