Pending absence leave notification re-send

Dear Colleagues,

I noticed that in my company unfortunately some employee(s) supervisor not approving or rejecting their employee(s) absences leave and notification(s) still pending with employee supervisor(s) for long time.

i tried to push them by re-sending a reminder email (in outlook not thru oracle application) and ask to re-approve/reject any pending absence(s)

my question: where can i found the exact notification link of the absence to re-send it thru email (as the first email that comes when user submit his absence for the first time) ?

Note:

My actual application version is R12.1.3

Database version: 11.2.0.3
