Requesters require few privileges to view scanned invoices, does it consume separate license?

Summary:

We have gone live on the production instance and our client users who are 'Requesters' need to View Scanned Invoices in the system for receipting purposes and invoice dispute issues. They are facing error as of now while trying to view these images and it is found that we need to add below 3 privileges/roles to their users for the same -
ORA_AP_WEBCENTER_IMAGE_INQUIRY_DUTY
ORA_AP_WEBCENTER_DOCUMENT_VIEW_DUTY
AP_VIEW_SCANNED_PAYABLES_INVOICES_PRIV
The question is do we need to add all 3 privileges and most importantly, will these privileges consume license separately? Kindly help us on priority as users are stuck because of this.
