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
