Error: 'get authenticatorAttachment' called on an object that does not implement interface PublicKeyCredential.

I managed to get this extension set up and working by manually creating the json and python files. With them correctly created I got it to work with my fingerprint on webauthn.io (I'm running Linux Mint, Firefox 153).

Unfortunately I get an error message after the fingerprint has been successfully read:

'get authenticatorAttachment' called on an object that does not implement interface PublicKeyCredential.

It looks like this isn't implemented in https://github.com/samveen/WebAuthnLinux/blob/main/js/webauthn-authenticator.js#L1448

I get the same error when trying to set it up on github.com, so it seems like this is needed to be implemented

I believe PR #3 should fix your issue. I'm just waiting for a few fixes to it to be implemented, and we'll be golden.

#3 is merged.

Next steps (over the next 2 days):

• Update version
• Publish

Looking forward to seeing the update.
