Working with Alert composer - Custom Alert

Hello Community,

Hope you all are well. I'm reaching to ask for your help with a custom alert in Oracle HCM.

The requirement is to capture the 'Projected End Date' (that has been made visible using Page Composer) on the 'Hire an Employee' page and notify the HR and Line Manager prior 28 days that the user's termination is on XX-XX-XX date. In the alert filter, I want to capture 'Fixed Term' EE's only. Awaiting your response.

Thank you,

Update: Notifications to Line Managers are working but not for hrRep. Below is the expression.

${AlertUtils.hrRep(emps.PersonId).UserName}
