onSessionInitialized

Type: function(holdToken)

Fired when a session is initialized. This is either when:

• a new session is started, e.g. when chart.startNewSession() is called, or when the user clicks on the "start over" button on the "session expired" dialog
• or when the chart is (re-)rendered with an already active session, e.g. after a browser refresh.

The holdToken parameter that gets passed into this callback is an object with the following structure:

{    
    "token": "wvXbB9MlHt",
    "expiresAt": "2020-01-06T10:58:44.715Z",
    "expiresInSeconds": 599
}

You can listen to this event to update a timer in your host page.
