Help with Plesk sidebar

Hello everyone. I am not very well versed in web hosting, and I'm trying to help a friend's troubleshoot some issues. When opening the Plesk site, on the Sidebar I only find the tabs for Mail and My Profile.

No Applications, Files, Tools & Settings, or any of the other options that from what I see, should appear.

Any idea on why this may happen? Is it possible he is not the owner of the domain, just a guest, so he has limited viewing options?

Thanks in advance
