Precsion 5680 - additional external fingerprinter reader?

So using Windows Hello with Windows 11 to login requires using the integrated fingerprint reader on the keyboard - all good and functioning perfectly - but what do I do when the laptop is plugged into the dock with the lid closed and I'm using an external monitor and keyboard.  Yes, I know I can use the PIN, but that means an extra few clicks etc.  I bought the Kensington Verimark Desktop Fingerprint Key to duplicate the functionality of the integral reader, but can't get it setup as first screen asks for Windows Password which I don't have as Windows Hello uses Biometric or PIN only.  Yes, I got in touch with Kensington support, and was told that as my laptop already has a fingerprint reader I couldn't add another one.

So, that's my scenario, and I'm mighty frustrated!!  All I want is to duplicate/extend the fingerprint read functionality to an external reader so that I can easily and quickly login to Windows 11 using my fingerprint when my laptop is docked with the lid shut.

Any pointers, suggestions, or advice greatfully received.
