Yes I did receive the initial text containing the token so no issue there.
The inject node in your sample flow injects a string "hello from node-red-contrib-whin". This is okay.
After about 3 seconds the debug node connected to the whin node displays:- payload: "Message Received"
Here is your sample flow I am using with my credentials.
