Kanban - Validation on change status

Hi, is there a way to execute an async operation inside the event, for example inside “onBeforeStatusChange”, to validate server-side if an item can change status?

Thanks!!!
I actually ends up change your snippet by returning true, and in the Promise chain setting the element back to his position if the validation fails. In this way i prevent the element from bouncing back and forward after the user interaction
