To trigger 3DS2 native, include the allow3DS2 parameter (if you using any version before 69) or the authenticationData.threeDSRequestData.nativeThreeDS parameter (if you using any version from 69 onwards) in your payment request and set it to true. This means that we can present the identifyShopper or challengeShopper. If this is not included we will only send redirectShopper in the response.
