Invoice information - Financial information tab missing

Within a new Scientific advice request, we received the information about invoice being available under the financial informaition tab of the IRIS Case, quote "invoice information will be available in the Financial Information tab of your IRIS case, displaying details such as invoice number, date, amount, and due date". 
I cannot find such a tab, can you help locating it?

The Financial Information tab appeared after validation was confirmed. Therefore, it is understood, that the e-mail informing about the invoice and payment is sent beforehand, when the "Financial tab" is not yet displayed in IRIS. See screenshot
