Survey Toolkit help on branch questions

Dear Epicollect5 communities, Greetings!
I have got a problem while integrating a private project with Google sheet by a script.
I have successfully connected one simple project by a default script provided in survey toolkit.

How ever I couldn’t get the right script for Branch type of questions.
Please help me by forwarding the script.

Thanks in advance !!!

This is a question for the Survey Toolkit developers

I think survey toolkit teams are away from this task to answer the questions. How ever I need it badly.
