Payables Invoice Inquiry (Read-Only custom role) needed for self service users?

Summary:

Payables Invoice Inquiry (Read-Only custom role) is triggering a full financial license due to the privilege which allows access to the payables work area even for view only. Is there a way to grant self service users access to the read only custom role for invoices?

Content (required):

This seems like a miss in the intent of the read only role as defined in Payables Invoice Inquiry (Read-Only custom role) (Doc ID 2360565.1) Please advise if anyone knows how to grant self service users a similar read only access as one would expect for folks that will not be processing payables data.
