In mongoDB, how do I get the id of an object created using insertOne() using async / await?

So I am creating a user object and inserting it into my mongo database using async / await.

Like so:

    await db.collection('users').insertOne({
      name: 'testName',
      age: 20
    });
    console.log('new user created');

I would like to get the Id from the object I have just added. I am currently doing this like so:

    const newUser = await db.collection('users').insertOne({
      name: 'testName',
      age: 20
    });
    console.log('new user created');
    console.log(newUser.ops[0]._id);

This works as I would like it to but it doesn't seem like the cleanest way to do this. Is there a better way to get the newly created object's id using async / await?

Here is your answer:

insertOne Returns: A document containing: A boolean acknowledged as true if the operation ran with write concern or false if write concern was disabled. A field insertedId with the _id value of the inserted document.

Example:

{
   "acknowledged" : true,
   "insertedId" : ObjectId("56fc40f9d735c28df206d078")
}
