Configure a external FIDO server for doing this webauthn registration & authentication

[amitt0488]

I have a separate FIDO server which provides all the APIs for FIDO (Webauthn) registration & authentication
How can I configure that separate FIDO server URL in openAM module or any other place for doing this registration & authentication ?
