How to send Email notification to both Project manager and Project administrator upon status change

How can I send email notifications to both the Project Manager and Project Administrator when the status changes to approved or rejected?

By default, as per the standard functionality the Project Manager receives an email notification, but I need to configure it so that both the Project Manager and Project Administrator receive notifications without using custom BI report notifications.

I am trying to achieve this using out-of-the-box functionality only. Please provide any inputs if you have encountered this before.
