Generate unique URL for sharing Google Forms?

Question

I have a Google Form that contains a simple question that can be answered "Yes" or "No".

The responses are being filled in a Google Sheet.

How can i identify who answered YES/NO?

Currently i have this code but apparently it does not fill my Google Sheets:

/*
This code shows how to get the edit response url of a 
programmatically submitted response to a Google Form
*/ 

// Replace the form ID by your own form
var formID = 'My Google Form ID';

function myFunction() {
  var form = FormApp.openById(formID);
  var response = form.createResponse();
  var items = form.getItems();
  var item = items[0];
  if (item.getType() == 'TEXT') {
    var textItem = item.asTextItem();
    var itemResponse = textItem.createResponse('What this does? I do now know.');
    response.withItemResponse(itemResponse);
  } 
  
  // Submit response
  var submittedResponse = response.submit();
  // Get submitted response attributes
  var values = {
    ID : submittedResponse.getId(),
    TS : submittedResponse.getTimestamp(),
    /* 
    Issue 4476: FormApp: getEditResponseUrl() produces invalid URL 
    https://code.google.com/p/google-apps-script-issues/issues/detail?id=4476
    */
    ER1 : submittedResponse.getEditResponseUrl(),
    /* Workaround from 
    https://code.google.com/p/google-apps-script-issues/issues/detail?id=4476#c2
    */
    ER2 : submittedResponse.getEditResponseUrl().replace(
      /\?edit2=.*/,"?edit2=" + submittedResponse.getId()
    ) 
  };
  Logger.log(values);
}
