I would like to get an alert when a task is marked as completed by the person I assigned the task to. Can an automation be created for this?

Question

I assign tasks to our secretary in the to-do section.

I would like to automatically get notified once the task has been completed without having to remember to search through her list of tasks.

Is an email good?

If possible to have a box on my welcome screen that would be better.

If not possible, email is good too
