Documents tab on USCIS online account

[fenomeno]

I recently got to know that I was scheduled for the oath ceremony but I never got any email alert. Luckily I was checking my USCIS online account every now and then. Among other things, the message online says that the oath ceremony notice will be available on the documents tab. However, I don’t see any documents tab on my USCIS online account. Does anyone know where the documents tab is located?
I was wondering if the USCIS website is functioning properly. Many thanks in advance.
