Sort Data Created via Aggregation

[TomTom]

I needed to create an aggregation based on the customer id, but inside the document I have an object with the customer details, like name and email.

Through a code I found, I learned to display in this aggregation the name of the customer that is generating the sum of the data, however, I can't sort these records.

I've tried using the instructions in the documentation, but it still returns the names out of order.

How can I order them?

    "query": {
        "bool": {
            "must": [
                {
                    "range": {
                        "datecreation": {

                        }
                    }
                },
                {

                    }
                }
            ]
        }

                }
            }
        }
    }
}

Result:
