Cannot use Touch ID on Magic Keyboard

I cannot use Touch ID on Magic Keyboard connected to a MacBook Pro 13,2 running Big Sur 11.5.2. Tried paying with and without the USB-C cable. Using a long-press in the Touch ID button locks the screen, but will not respond to open using touch. I also reconfigured the finger prints from the MacBook Touch ID button.

MacBook Pro (13-inch, 2016, Four Thunderbolt 3 ports)

Model Identifier: MacBookPro13,2

Your Intel Mac does not support the feature

external magic keyboard TouchID compatibility is limited:
