I am using the stream_rails gem for my Rails App and want to develop a real time notification system in my app. For this purpose, I want to be able to generate a readonly token. Currently when I was going through the documentation here: http://getstream.io/docs/#readonly-tokens
it did not provide any steps to generate readonly token for ruby app. Can someone please help me with this information on how to get one? Also please let me know if this readonly token has any expiration time (or) is it valid for the lifetime?
