When using the getRegisterPendingIntent and getSignPendingIntent APIs of the Fido2ApiClient in Android, why can't face unlock be used when creating credentials or generating assertions with credentials? Or is this possible to set in the PublicKeyCredentialCreationOptions or PublicKeyCredentialRequestOptions?
When testing on a phone that supports both face and fingerprint unlock, I've found that I can only create FIDO credentials and generate assertions using my fingerprint or screen PIN.
