How can i make a messagebox at the same time with a notification sound/alert?

[Rocky Rocss]

-continuation of my question:

example for HumanResource. if an employee's contract is about to be expired, the system will notify the HR system with a messagebox and at the same time with a sound/alert, like a "buzz" or "beep" to notify the HR that the employee should renew their contract.

please help. Thank you!
