When having a struct like this:

type TestStruct struct {
        ID   objectid.ObjectID `bson:"_id"`
	Desc string            `bson:"desc"`
}

func Create() {
       t := TestStruct{
              Desc: "Testing 1234"
       }

       .....InsertOne(context.Background(), t, nil)
}

This creates a byte[12] (Binary) value in the database instead of an objectID. When removing the `bson: "_id"` tag. It automatically creates a correct objectID. But then there is no bson mapping to the ID field in the struct.
