Windows Hello - External USB IR Camera

Has anyone managed to get a modern Latitude 5*** laptop to work with an external USB Windows Hello IR camera whilst the lid is shut?

After some googling I see this has been an issue in the past & seems to be related to power settings, see: ‎Windows Hello with lid closed | DELL Technologies

I have tried disabling the internal camera and changing the registry keys in the above article & disabling “Enable Lid Switch” in the BIOS.

I have a Lenovo laptop and everything works perfectly fine.
