New Confirm Receipt functionality doesn't seem to be working

Summary:I have been testing the new Confirm Receipt functionality which according to the IA and supporting documentation, should be working in DEV5 given the deployment of 25C and is a new functionality within this release.

I have entered an invoice (BH Test 123) against PO PNU****106, this PO hasn’t been receipted and the invoice goes on a receipting hold. I have run the Confirm Receipt process which generates the expected notification (see below):

However, according to the 25C documentation I should also be seeing the confirm receipt option on the requisition screens, but currently I’m not, so is the documentation incorrect and there is further setup needed?
