I tested the same and got the same result.
I suppose BigSur doesn't support the button feature in its
firmware.

If it does, you should see "ACPI: Power Button (FF) found" in
boot message and you will see a /proc/acpi/button directory.

If the button event is properly processed, you can see
"button power 00000080 00000000"
line when you cat /proc/acpi/event.

Thanks,
