How to recover metadata from Driver framework events

In the Event Manager of the Driver Framework, the NewEvent() method allows adding some metadata. How can we recover this metadata from inside the event server by subscribing to new events?

string lpr = eventId.Length > 4 ? eventId.Substring(4) : "";
var eventData = new Dictionary<string, string>();
eventData["LPR"] = lpr;
_eventManager.NewEvent(Constants.Camera1.ToString(), Constants.AnalyticsEventReferenceId, eventData);

We figured it out! We had to cast the BaseEvent to AnalyticsEvent and then use Event.ObjectList to find the additional metadata items.

var aEvt = baseEvent as VideoOS.Platform.Data.AnalyticsEvent;
foreach(var o in aEvt.ObjectList)
{
    Console.WriteLine($"Name: {o.Name}, Value: {o.Value}");
}
