Import supplier invoice not found


I recently installed ERPNext v13 on a VM
I noticed that in “Buying>regional>import supplier invoice”

I get this error

Page import-supplier-invoice not found
The resource you are looking for is not available

I checked the local files in “/opt/bench/erpnext/apps/erpnext/erpnext/regional/doctype”
the directory “import_supplier_invoice” already exists.

idk why is this happening, is it important? is it not working by default?
