Accessing "Magellan BI & Reporting Release Notes"

Reading the Data Protector 23.4 documentation, specifically "Magellan BI and Reporting Integration", there is a link named "Magellan BI & Reporting Release Notes" recommended to be read.

However when I follow this link, I get a message that my user does not have access rights to the page. I tried to use an old-time OpenText user I had created in the past for a different product, but that user does not have access.

And when I used my MicroFocus account that has access to Data Protector, I also could not access the document.

So how is this intended to work?
