Get access to the chat using Twitch Unity plugin

Hi, I am using the plugin to integrate Twitch into Unity and I have to say that logging in is very easy to do.
However, I do not understand how to get access to the chat and read all the messages the streamer would receive. I have been reading the API for days but I cannot find anything related to the plugin given by the website.
Actually, the thing I could do is implementing TcpClient in the script and then using StreamReader and StreamWriter in order to log in to the chat and read the messages, but I would need an access token to do so.
I have already found a way to get the access token without the Twitch Unity plugin but I would prefer to keep on using it because it is intuitive. So, my question is: how can I get access to the chat using the plugin?
I will wait for your answer. Thank you in advance.

Those eventsub types for chat were added to eventsub after the plugins were released.

And the plugins have not been updated to support the new type. When/if that will occur I don’t know

Thank you for your answer. Now, I’m trying to create an application which reads the chat using EventSub via WebSockets. Unfortunately, I’ve encountered another issue but I’m going to open a new topic.
