Aurora R15, Keyboard KB900, Zoom issue

KB900 was working fine with my Aurora R15 until the latest Zoom update. Since the last update, collaboration keys stopped working (not lit up). Windows 11 Pro, Dell Peripheral Manager app version 1.7.4, and the keyboard's driver version 1.2.0.31. I bought this keyboard from the Dell official store on Amazon. I tried to call Dell customer service, but the operator told me that they could not help me because I didn't buy it from the official Dell store, and now I have only two options: ask Amazon support for help (which is crazy) or to go to a Dell retail store (honestly I can't find any Dell retail store in the vicinity- have to go to another town, but even if I had one how could I show them what my problem is? Should I bring the entire workstation with me?). I also tried to register it on Dell.com (Dell Product Registration | Dell US ) to get support through online customer service. I can't do that since it gives me only one option- to detect a PC, which is not a product I'm trying to register. How can I solve my problem or get any support from Dell, please?
