object.deselect([ticketType])
Returns: Promise<void>
Deselects a selected object.
object.deselect();
generalAdmissionArea.deselect('adult');
The promise resolves when deselecting succeeded. That includes releasing the hold on the object, if a session is active.
It is rejected if the object could not be deselected - e.g. because the call to release the hold failed.
