Adding jsPsych to Qualtrics

Hi, I am trying to add the kirby delay discounting task into Qualtrics. I have downloaded the JavaScript code from OSF: https://osf.io/wkf2z/ However, since Qualtrics has updated the platform, old tutorials that explain this process do not work anymore. I have also tried several things with the new JavaScript feature in Survey, but when I preview the experiment I only get a blank space. Does anyone have experience with adding a JavaScript experiment in Qualtrics, who can help me? Is it still possible? I have completed some courses in JavaScript, but I am still a beginner. Thanks in advance! Regards, Giannina
