[keycloak-user] Execution Flow

Hi All, I'm a little confused with configuring alternative execution flows. I currently have the follow configured. Cookie Username Password Form TOTP Configured? <- Alternative OTP Form <- Optional No, SMS then <- Alternative SMS Auth <- Optional As you can guess, I want SMS auth to trigger if OTP is not configured. At the moment it seem that if OTP isn't configured, the OTP Form is skipped and authentication is successful and SMS is skipped. Is there a way to tell keycloak the if OTP is not configured then the 'TOTP Configured?' execution flow has failed, so the 'No, SMS then' execution flow is actioned? Thanks, Stuart.
