How to parse a site that uses ajax?

Question

Parsing

Hello guys. There is a need to fill the site with content, but it is extremely tedious to do this with handles. Therefore, the idea arose to write a parser. The parser will be written in c# AngleSharp.

Surgeon's tool: c# > AngleSharp
Subject: anime.org parse
: links to episodes, voice acting, player. They use a codec there, but besides it, there is also sibnet, etc.

I don’t understand how to get a list of all the episodes for each voice acting. help please!!
