/**
 * Coviu Session API
 * Coviu provides a session based API for creating and restricting access to coviu calls. The core concepts exposed are* Session: A coviu call that occurs between two or more parties at a specified time, and has a finite duration.* Participants: Users who may participate in a coviu call.Participants join a call by following a session link in their browser, or mobile app. The session link identifiesthe participant, including their name, optional avatar, and importantly their role. As such, it is important thateach person joining the call be issued a different session link, i.e. have a distinct participant created for them.A participant's role identifies whether that user may access the call directly, or if they are required the be let inby an existing participant.
