The eventHoverHandling property (string) determines the event hover action.
The default value is "Bubble". With this value set, the JavaScript Scheduler component will display a callout when you hold the mouse cursor over an event.
You can set a custom DayPilot.Bubble object that will be used to display the popover using the bubble property.
