How to Enable Absence Approval Notification logged via timesheet

Summary

The line manager is not receiving a notification that an absence is for approval, if the absence was logged via timesheet in Time and Labor.

Hello,

Does anyone have an idea how we can configure the notification to be sent to a manager when an absence entry was logged via Timesheet. Currently, we are using the Project Time Approval workflow .and the current setup is that the timesheet is for the Project Manager's approval when submitted, but the absence approval should be routed to the line manager separately.
