mongo-go-driver で bson.RawValue を使用して _id でドキュメントを検索する方法は?

<code class="go">import (
    "context"
    "encoding/hex"
    "encoding/json"

    "go.mongodb.org/mongo-driver/bson"
    "go.mongodb.org/mongo-driver/bson/bsoncodec"
    "go.mongodb.org/mongo-driver/bson/bsonprimitive"
    "go.mongodb.org/mongo-driver/mongo"
)

func findDocumentByID(collection *mongo.Collection, ctx context.Context, id string) (*bson.Raw, error) {
    objID, err := bsonprimitive.ObjectIDFromHex(id)
    if err != nil {
        return nil, err
    }

    value := collection.FindOne(ctx, bson.M{"_id": objID})
    return value.DecodeBytes()
}</code>

<code class="json">{
  "_id": "5c7452c7aeb4c97e0cdb75bf",
  "name": "John Doe",
  "age": 30
}</code>

<code class="go">id := "5c7452c7aeb4c97e0cdb75bf"
value, err := findDocumentByID(collection, ctx, id)
if err != nil {
  return nil, err
}</code>
