You can configure it in such a way that the task can wait for a certain duration or until a specific date & time, or you can configure the wait type as “Signal”, which waits for some manual intervention to get completed. If you have configured the wait type as “Signal” and run the workflow, you can see that the task is in progress, waiting for an external signal to continue. You can manually update the task status to “Completed” directly from the UI, as shown below.
