Book leave against a balance you can see, with the team calendar showing who else is off before you request rather than after. Payslips and documents are on your own record.
The directory shows role, team and manager, and is current because it is a view of the personnel record rather than a second list somebody maintains.
It will not approve your leave. It routes the request to the right person with the context to decide, and shows you where it is.

On your own record, without an email.
