In Cloud Functions, what is the syntax for writing a JSON to the Map data type in Cloud Firestore?

I am writing a Google Cloud Function that receives a Webhook JSON payload, parses the JSON and writes the data to the Cloud Firestore.

I have a map of strings inside of Cloud Firestore at collection.("orders").doc():

customerNote (map)
     customerNote1 (string)
     customerNote2 (string)
     customerNote3 (string)

For a simple string, the syntax for writing to the Cloud Firestore within Cloud Functions could like like:

await admin.firestore().collection("orders").doc().set({
orderNameInFirestore: data.orderNamefromJSON
})

What does this cloud function look like for a Map of Strings?

Firestore can accept and store arbitrary JavaScript objects (with some limitations). As an example:

const myMap = {"key-one": "abc", "key-two": 123};

await admin.firestore().collection("orders").add({
  mappedData: myMap
});

the above will work just fine so long as the map is of reasonable size.
