Nitrokeys FIDO2 / Nitrokey 3

Please help me debug this.

I’m trying to use https://confer.to in an AppVM in Qubes OS with Brave Browser.

I can only make it work on sys-usb.

When I try to use it in another VM, I connect to Confer.to with Brave Browser, Nitrokey 3C starts bliking blue, and after I touch it, I get this message:

```
Your device can’t be used with this site
confer.to might require a newer or different kind of device
```

Hello, I just tried on QubesOS and it works when my NK3 is attached to the qube.

On your same qube are you able to make your Nitrokey work with https://webauthn.io/ ?

Additionally what is your Nitrokey firmware version?
