Query to get payment description from payable payment page

Summary:

Hi everyone, I am building up a query for extracting all payable payment informations.

I cannot find the payment description that I am able to see on the web page.

In the api response body is called PaymentDescription

 "CheckId": 300100261773606,
  "PaymentId": null,
  "PaymentReference": null,
  "PaperDocumentNumber": null,
  "PaymentNumber": 192,
  "PaymentFileReference": null,
  "PaymentProcessRequest": "300100261773606",
  "PaymentAmount": 10,
  "PaymentDate": "2020-04-01",
  "AccountingDate": null,
  "PaymentDescription": "Manual_Payment",
  "ConversionRate": null,

I am looking into the iby_payment_all where I find all the other informations, also the payment_reference_number. But also looking into all the other table related to payment the description is not visible.
