That's a list of USB VID and PID, which you can find for your device using the lsusb command. If your U2F device isn't on that list, you can raise an MR like https://github.com/snapcore/snapd/pull/10642 to get it enabled.
Some might debate the wisdom of the OS vendor maintaining a list of blessed devices - but it is what it is.

This is actually fixed for me on 22.04
22.04 moved Firefox into snap, and snap has a whitelist of permitted U2F tokens: https:/ /github. com/snapcore/ snapd/blob/ 2.58.3/ interfaces/ builtin/ u2f_devices. go#L43
