如何使用Go官方驱动执行addToSet？

import "go.mongodb.org/mongo-driver/mongo"

client, err := mongo.NewClient(options.Client().ApplyURI("mongodb://localhost:27017"))
if err != nil {
    log.Fatal(err)
}

ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()

err = client.Connect(ctx)
if err != nil {
    log.Fatal(err)
}
defer client.Disconnect(ctx)

collection := client.Database("mydb").Collection("mycollection")

doc := bson.D{
    {"name", "John"},
    {"age", 30},
    {"city", "New York"},
}

update := bson.D{
    {"$addToSet", bson.D{
        {"myarray", doc},
    }},
}

filter := bson.D{
    {"_id", bson.D{
        {"$eq", "123"},
    }},
}

_, err = collection.UpdateOne(ctx, filter, update)
if err != nil {
    log.Fatal(err)
}
