In Odoo 15 there is partner ledger report in accounting module (enterprise).
I want to edit the footer of this report.

I have checked all QWeb views from Settings->Technical->Views

I found the QWeb views that handle the viewing part of the report. But the footer is not part of those files.

I have also tried changing the Document layout form settings and reached the conclusion that its not used in Partner Ledger Report

I want assistance is reaching the footer code.

EDITED:

Adding image for reference
