Custom Background - Unable to Add

I am following the instructions for adding a custom background image (iMac - OS Sonoma 14.5). I have a Zoom Workplace Pro account

1. In the navigation menu, click Room Management then Zoom Rooms.
2. Click the Account Settings link.
3. Click the Account Profile tab.
4. Under Setup, locate the Background image for Zoom Rooms setting.

But when I get into Zoom Rooms there is nothing else, no account settings link or account profile tab -- what do I do now?
