Authentication via Yubikey FIDO2 for M356

[kkulshre]

I am successfully using openconnect-sso for M365 AzureAD authentication for my company VPN. As MFA i need to use the Microsoft Authenticator App though. We have been issued with Yubikey 5C for althernative MFA also, but using this for openconnect-sso is currently not possible. The browser window does not open a dialog for PIN entry and authentication via FIDO2. I looked into the QtWebEngine development history and found that Qt 6.7 added FIDO2 user verification support recently in https://bugreports.qt.io/browse/QTBUG-90938
Would it be possible to have this feature in openconnect-sso also? Thanks.
