A pending status on a work item indicates that the work item is open, but progress is paused or halted temporarily while the organization is waiting for information, a decision, a signature, or other events from a party outside the organization. A pending status does not alter the goal times or deadline times for the assignment.
Your flows can use the standard router activity named Work-.ToDeferredWorkbasket to place work items with a pending status into a workbasket named deferred@org.com.
