Short answer: You can't.

WebAuthn by design wants to preserve user privacy, and so there's no mechanism for an RP to silently query for if the machine recognizes a list of credential ID's to know ahead of time if auth has a chance to succeed. You need to prepare to invoke WebAuthn and handle the failure accordingly.

It's clunky and suboptimal from an RP's perspective, but then that's a common complaint by RP's looking to go passwordless 😂 😭
