Is it possible to convert hex payload to readable schema (steam)?

Question

Node.js

Understanding how csgo interacts with servers. I use nethook2 and nethook analyzer2.
In many methods, you can observe both payload and an understandable data scheme, the screen is below.

I haven't worked much with a buffer before, but I understand that a buffer is sent to the server which is assembled using Buffer.contcat([Buffer(header), Buffer(data)]).
And there are methods where the nethook analyzer does not show a clear data scheme, an example.

So, I understand how the header is generated, but is it possible to somehow bring the payload part, where the data is located and understand what scheme is used to communicate with the server and what specifically needs to be sent.
