How to view the actual time spent on tasks in Scrum process?

Hi guys,

Can we do that

We are using Scrum process workflow (https://www.visualstudio.com/en-us/docs/work/guidance/scrum-process-workflow). During the Sprint, we fill in Remaining Work field of tasks. After a Sprint, we need to know actual spent time on tasks in a product backlog item so that we could update the actual effort for later reference. 

Thanks,
