I am trying to add an OTP service for a mobile app. The idea is: When user inputs mobile number and clicks on Get OTP button, the OTP service should be triggered and populate in the next screen. But I am not able to download any OTP tool from the Marketplace. I am using Mendix 10.1 version. Is the OTP tool only accessible within lower versions of Mendix? If so, how do we add OTP in the latest version?
