The Program is running on the streamers computer, which therefore authorizes with his Account and should me give permission for his channel, right? Since the LISTEN does not return an error, the channel must also be right, otherwise the scope wouldn’t be valid, right?
It is actually the PubSub I am using, but the UUID is generated internally by the python package, and not from the response. My bad tho… 
Thanks for the response, I guess I will give the discord a try, and ask there for help, if anyone had similar issues with the package.
