How to bulk import employees using visual builder add-in in excel?

I need to import +1000 employees into the system, I have an XML template that was provided for this purpose, nevertheless it is complex and no time-friendly including data into this XML.

I reviewed this documentation: https://docs.oracle.com/en/cloud/paas/visual-builder-addin/3.4/excel-developer/create-layouts-excel-workbook.html#GUID-13714A67-AFC0-4836-A1BC-E06CD0179C4F and found that there´s a way to create a layout in excel using Visual Builder.

I followed the steps but I´m having trouble with the URL for the catalogs. I used a URL built as the sample in documentation (i.e: https://my-service-host/fscmRestApi/resources/latest/invoices/describe). But I´m obtaining errors such as: The requested resource could not be found. (VBAFE-00107).
