[keycloak-user] How to create a custom OTPPolicy?

Hello, I need to create a custom OTPPolicy. Unfortunately, OTPPolicy policy is created via the constructor and not via a factory: public static OTPPolicy DEFAULT_POLICY = new OTPPolicy(UserCredentialModel.TOTP, HmacOTP.HMAC_SHA1, 0, 6, 1, 30); (from the class org.keycloak.models.OTPPolicy) Any help will be appreciated.
