I see in the Shiny reference app that a challenge is passed in an assertion request using : assertionRequest = publicKeyCredentialProvider.createCredentialAssertionRequest(challenge: challenge)
But how can I send other properties such as allowCredentials and specific the list of cred ids that are acceptable. This is part of FIDO2/webauthn. But I don't see how to pass the same request detail using the Shiny example methods.
