help me understand this client-side packet reception code i found online?

hey guys, I've got a spigot plugin working that sends packets to the client through a defined channel (im pretty sure at least), and all I need now is to get a fabric client-side mod working that allows me to extract that info. I found some code online from a guy who did exactly that in early 1.21, and the code looks mostly functional still, I'm just struggling to understand how to actually get my information into a useable state for the mod... any help would be GREATLY appreciated!!

Sounds like you'll need to figure out what format the plugins actually send stuff in. Didn't know they could send non-vanilla packets tbh.

Usually you'd use a StreamCodec to serialize/deserialize, but if both sides don't use the same format 🤷
