This event is emitted whenever an annotation is either clicked or touched (on devices with touch capabilities) as well as when an already selected annotation receives a click or touch event.
Use this event to add custom behavior or prevent default ones from happening on press.
Please note that this event will not be fired for annotations which are not editable. If you still want to detect clicks for such annotations, for example, to show a focus ring when clicked, you can use custom renderers to made a clickable area above each annotation. This method is described fully in our Knowledge Base.
