Information about the current availability of an agent while a user is waiting to be connected. If these are not set the web chat will provide generic messaging letting the user know that a request for an agent has been sent.
Note that only one of these fields will be used by web chat if more than one has been assigned a value. Priority first goes to estimated_wait_time, then position_in_queue, and then message.
