How can I obtain sample data to test the billedReconciliation export API?

I am looking to test the new version of the billedReconciliation export API. Is there any way to obtain sample data to do so? I have tried using invoices from the documentation and GitHub readme of the sample codes, but without success. The API documentation that I am referring to can be found at these links: https://learn.microsoft.com/en-us/graph/api/partners-billing-billedreconciliation-export?view=graph-rest-1.0&tabs=http and https://learn.microsoft.com/en-us/partner-center/developer/billed-invoice-reconciliation. The following are the relevant invoice numbers: G012040490 and G016907411.
