Procurement Agent bulk upload via Visual Builder Add-in

Summary:

When trying to upload Procurement Agents in bulk through Visual Builder Add-in (using the REST API's available), we notice that Create & Update functionality is not enabled.

Content (please ensure you mask any confidential information):

Through the Visual Builder Add-in we can perform a download (get all) of the procurement agents.

However, the actions for Post or Patch do not seem possible, even though the REST API's to do the same are available.

Anyone any idea if more setup is required in VB Add in? Am I missing something or is it simply not possible at this time?

I know export/import CSV is available, but the format of this Visual Builder table is much easier to maintain procurement agents.
