Assignment of tasks

I would like to assign task 1 from project X to person A. How do I do this so that person A receives a notification that the task has been assigned to him?

Hello there,
Sadly, there is no option to receive information when a project or task is being assigned to a user but there is a plan in the future for that option to be added.
I will forward this to our production as a feature suggestion!
