New Magic Keyboard F-keys not controlling volume on iMac

I just bought a new Magic Keyboard for my iMac because the old one quit. I can't get the f keys to control the volume. I have followed the steps but nothing changes. f10 and f 12 do nothing while f11 brings me back to the desktop. HELP!!! When I go to System Preferences-Keyboard-Shortcuts, it only gives me very limited options to access 7 fn's.

iMac 27″, macOS 12.7

Just to confirm:

Is this new Magic Keyboard any of these model: A3118, A3119, or A3203? These were all introduced by Apple in 2024.
Is your Mac still running macOS 12.7 (Monterey)?

If both are true, full keyboard features will only be available on Silicon Macs running macOS 15.1 (Sequoia) or later.

A3118 = Magic Keyboard with Touch ID for Mac models with Apple silicon (USB-C)
A3119 = Magic Keyboard with Touch ID and Numeric Keypad for Mac models with Apple silicon (USB-C)
A3203 = Magic Keyboard (USB-C). Apple indicates that it is compatible with the 27" Intel-based iMacs released in 2019 and 2020, and the iMac Pro (2017) – the only three Intel-based Macs that can run macOS 15.1.

Magic Keyboard with Numeric Keypad for Mac models - Apple appears to be model A1843, a keyboard released in June 2017. It has a Lightning connector for recharging and initial pairing (but can be connected to a Mac's USB-C port using an appropriate adapter), and requires macOS 10.12.4 (Sierra) or later. I do not believe the Compatibility list for this one is complete, as it omits a lot of iMacs that can run Sierra or later.
