Exam UiARD topic 8 question 129 discussion

A developer is working on their first project design involving Orchestrator interactions. An email needs to be sent to the process owner at the end of each transaction. The process owner is only expected to change once a year due to role changes within the company. The transaction number is the employee ID and must be included in the email to the process owner.
Based on best practices, how should the process owner email and employee ID be set?
