Hi Oren,

indeed you are right, you read the data from your collection first to get a JSON item like this:

{
  "_id": "00001",
  "_owner": "ffdkj9c2-df8g-f9ke-lk98-4kjhfr89keedb",
  "_createdDate": "2017-05-24T12:33:18.938Z",
  "_updatedDate": "2017-05-24T12:33:18.938Z",
  "title": "Mr.",
  "first_name": "John",
  "last_name": "Doe"
}

the you update the fields you need and continue according to the example here:
