Changing a script based experiment to a builder format

Hi,
I am using Psychopy version 2022.2.5 on Mac (MacOS sonoma 14.4.1).
I have written a script to perform a karaoke like experiment (attached), but I want to use it online. I understood the easiest way would be to rebuild it using the builder so the compilation to JS would be automatic. But, I don’t succeed in doing so. Would appreciate any guidance.

The script and excel file are attached.
