I need to know the code of the sample application.

I need to know the code of the sample application.

Hello,

Recently I use Zoho Creator to create an app for specimen management in my laboratory. I want to add a feature to create a label for each specimen that I checked in, and I find this sample application similar to my need ( https://creator.zoho.com/sampleapps/preview-and-print ) However, I can't download or add this application to my application. I want to edit the application so I can see the deluge code.


Please help
