Plantronics Javascript SDK types explanation (e.g SpokesResponse, SpokesEvent etc)

Hi everyone, I'm currently working on integrating plantronics javascript sdk to my angular project. There are several events that are being called by the sdk with different responses. For e.g  there is a SpokesResponse object that is passed in the spokes.Device.events.  The question is, do we have some kind of documentation that explains all these params and their possible response types/values with explanations ?
