Cognito Custom authentication flow between web app and mobile app

Hi all I have a login flow with Cognito in the web app and mobile app like this: Web app -> login with user/password -> cognito -> OTP -> validate success -> Home page But now I have another requirement: Cognito should skip the OTP process when the user logs in with a biometric method (face, fingerprint..). The login process will become like this: Web app -> login with biometric -> cognito -> Home page. (skip the OTP issue and validate the OTP steps) How can I achieve this? Thanks
