As a way of initializing a form record, I want to fill and submit a google form with apps script. The key bit of documentation for form.createResponse() is this
Creates a new response to the form. To answer a question item, create an ItemResponse from the item, then attach it to this form response by calling FormResponse.withItemResponse(response). To save the assembled response, call FormResponse.submit().
do I need to new FormResponse() or how do I make this happen?
