Absence Calendar page to add Absence Balances

Summary: Hello,

Please assist on the following…

I am using the Line Manager dashboard → Absence Calendar page → Workforce Management - Absence Calendar Details Real Time subject area.

The request came to add Absence Balances for the Absence Calendar page: Annual Entitlement, Carryover, Submitted, Balance, but I can't locate those metrics with Workforce Management - Absence Calendar Details Real Time subject area.

The Annual Working Duration and Carryover fields all blank:

Is it possible to add Absence Balances with Workforce Management - Absence Calendar Details Real Time subject area fields?

Do we have any samples or guidance on this?
Could you please guide on the Absence Calendar and Absence Balances.
