Google Form to Slack threaded message - forms

Question

In Google Form, on submit, I want to send a new message as one of the fields from the form and want to include the rest of the form fields as threaded messages in to the parent message.
I manually captured one of my thread_ts and successfully sent threaded messages. But I do not know what is the [best] way to get thread_ts id as I submit the form.
var channel = 'xxxx';
function onSubmit(e) {
var response = e.response.getItemResponses();
var Parent = response[0].getResponse();
var Thread = response[1].getResponse();
var Thread2 = response[2].getResponse();
var message = '#Test - ' + Parent;
var payload = {
"payload": '{"text": "' + message + '"}'
//"payload": '{"channel": "xxx","thread_ts": "1571950486.000500","text": "' + Thread + '--' + Thread2 + '"}'
}
var options = {
"method": "post",
"payload": payload
};
UrlFetchApp.fetch(webhookUrl, options);
};
I do not get any errors.

Here is how I was able to do it:
var webhookUrl = 'https://hooks.slack.com/services/***/***/***';
function SendtoSlack(e) {
var formResponse = e.response;
var itemResponses = formResponse.getItemResponses();
for (var i = 0; i < itemResponses.length; i++) {
switch (itemResponses[i].getItem().getTitle()) {
case "Client":
var Client = itemResponses[i].getResponse() || '';
break;
case "Day":
var date = itemResponses[i].getResponse() || '';
break;
case "Time":
var time = itemResponses[i].getResponse() || '';
break;
case "Device":
var Device = itemResponses[i].getResponse() || '';
break;
case "Browser":
var Browser = itemResponses[i].getResponse() || '';
break;
case "Geo":
var GEO = itemResponses[i].getResponse() || '';
break;
}
}
var redirectAlert = '#***'+' - ' + Client;
var payload = {
"payload": '{"text": "' + redirectAlert + '"}',
}
var options = {
"method": "post",
"payload": payload
};
UrlFetchApp.fetch(webhookUrl, options);
var webhookUrl1 = 'https://slack.com/api/conversations.history?token=xoxp-***-***-***-***&channel=***&pretty=1';
var slackJSON = UrlFetchApp.fetch(webhookUrl1);
var slackJSONObject = JSON.parse(slackJSON);
var ts = slackJSONObject.messages[0].ts;
var threadedMessagePayload = {
"payload": '{"thread_ts": "' + ts + '","text": "' + '`\nDevice: ' + Device + '\nBrowser: ' + Browser + '\nGeo: ' + GEO + '\nReported Date & Time: ' + date + ' ' + time + '"}',
}
var optionsForThreadedMessage = {
"method": "post",
"payload": threadedMessagePayload
};
UrlFetchApp.fetch(webhookUrl, optionsForThreadedMessage);
}
