If you specifically need to store an integer as a 32-bit or 64-bit value, you can use a driver-specific method or construct BSON objects using the appropriate BSON data type for integers. For example, in the Node.js MongoDB driver, you can use the `Int32` and `Long` constructors from the `mongodb` package:

```javascript
const { Int32, Long } = require('mongodb');

const myInt32 = new Int32(42); // Creates a 32-bit integer
const myInt64 = new Long(9007199254740991); // Creates a 64-bit integer
```

Remember that choosing the appropriate integer size can help optimize storage and performance within your MongoDB application. Use `Int32` for smaller value ranges and `Int64` for larger value ranges as needed.

For example, in a Node.js code with the native driver use `ObjectID()`:

```js
const mongodb = require('mongodb')
const ObjectID = mongodb.ObjectID
collection.findOne({_id: new ObjectID(idString)}, console.log)
```

On the other hand, in the MongoDB shell and many other MongoDB libraries like Mongoose, we employ `ObjectId()`. The following is the MongoDB shell code:
