Events TicketCalendar - how it works?

[yuri0001]

Hi!
In OTRS 3.3.0 beta3 I saw the new feature - Events TicketCalendar!
I'll try to configure it SysConfig. I'll create new Dynamics fields for StartTime & EndTime, enabled them in CustomerTicketMessage and some other screens/
Placed their names in Frontend::Agent::Dashboard::EventsTicketCalendar - in DashboardEventsTicketCalendar::DynamicFieldEndTime/StartTime & enables them.
Create ticket in customer interface & entered this Date/Time
But I see nothing displayed in Events TicketCalendar in Dashboard.
What I need configure more & what I CAN see there?
I don't found any lines in manual about it.

I finally found in the documentation - about it - Chapter - Dashboard.
I'll configure it as I wrote in first post & now in manual, but also see nothing in Calendar on Dashboard screen.
UPDATE: Yes, it works properly!!! It's where my bug - I was confused by the order of fields on the screen and the start date was more than the end date.
After correcting the error, all earned.

you have to define the Queues for the dashlet

Now, all works fine. but I can't configure displaying Ticket number. What variable I must use in Frontend::Agent::Dashboard::EventsTicketCalendar-->TicketFieldsForEvents - that defines the ticket attributes that will be displayed in the calendar event overlay windows.
I'll tried TicketNumber - but to no avail - it displayed empty field instead.
