The K64709WW kensignton fingerprint key has an LED: it is the "white locK symbol" visible on the top side of the digitec image.
I have not tested it with windows 11, but on windows 10 this key appears under: "USB Input Device / HID-compatible fido", and NOT under "Biometric devices".
My understanding is that this key is NOT compatible with windows signing, but is compatible with FIDO2 via browsers.
There are a few sites that allow you to test a fido2 key with your browser, e.g.
https://www.token2.com/tools...
Most recent browser support FIDO2 authentication via USB HID, without any driver installation.
