AMF Issues - Trying To Make a Miniclip Config - Experienced Config Makers

[Pestilence 4]

So I'm making a config and got a bit stuck

The site uses gzip, deflate, br encoding and amf (Action Message Format)

 

The problem is I can't find the parameters for the username or password, when I'm on fiddler it just gives me this:

 

 

                    

 

 

 

 

I've already added headers such as content type and Accept-encoding but I've got nothing

 

Here is the source I receive when I call the parameters and  'username' and password'

 

 

What should I call the parameters or am I doing something wrong?
