Benefits lifeevent occured date in email template by using emps resource in Alert Composer

Hello Team.

How can we add the LifeEvent Occured date in email template for the emps Resource for Alert Composer

or

Please help us in selecting correct resource such that alert should be triggered when an employee is enrolled in "Employee Supplemental Life" plan and should submit the required documents for example - Proof of good health certificate needs to be submitted. This alert is needed to send on Immediate and also as reminder email for 30 days such that in email template it should be life event occurred date +30 days.

Thanks
