how to nest JSON inside 'data:'{} object for POST fetch request?

I've created my own form in HTML+JS and sending a fetch request to my Xano Jobs DB.
(I have prevented the default form handling and doing my own fetch request. It is working as it is sending the 'created_at' date)

From my JS code, my JSON object looks like the below snippet.

How can I make it nested one level deeper inside 'data:' {} as it appears to me Xano expects this way?
The input for my POST endpoint is Type: json / Name: data

I can't map my JSON data if it's not data.job_type - but at the moment i don't have 'data'

I'm new to JS so just hacking and slashing 😆
I'm guessing I somehow need to put the FormData inside another object??[app.js]
