     * Create a new Change Stream, watching for new changes (insertions, updates,
     * replacements, deletions, and invalidations) in this database. Will ignore all
     * changes to system collections.
     *
     * @remarks
     * watch() accepts two generic arguments for distinct use cases:
     * - The first is to provide the schema that may be defined for all the collections within this database
     * - The second is to override the shape of the change stream document entirely, if it is not provided the type will default to ChangeStreamDocument of the first argument
     *
     * @remarks
     * When `timeoutMS` is configured for a change stream, it will have different behaviour depending
     * on whether the change stream is in iterator mode or emitter mode. In both cases, a change
     * stream will time out if it does not receive a change event within `timeoutMS` of the last change
     * event.
     *
     * Note that if a change stream is consistently timing out when watching a collection, database or
     * client that is being changed, then this may be due to the server timing out before it can finish
     * processing the existing oplog. To address this, restart the change stream with a higher
     * `timeoutMS`.
     *
     * If the change stream times out the initial aggregate operation to establish the change stream on
     * the server, then the client will close the change stream. If the getMore calls to the server
     * time out, then the change stream will be left open, but will throw a MongoOperationTimeoutError
     * when in iterator mode and emit an error event that returns a MongoOperationTimeoutError in
     * emitter mode.
     *
     * To determine whether or not the change stream is still open following a timeout, check the
     * {@link ChangeStream.closed} getter.
     *
     * @example
     * In iterator mode, if a next() call throws a timeout error, it will attempt to resume the change stream.
     * The next call can just be retried after this succeeds.
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * try {
     *     await changeStream.next();
     * } catch (e) {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *       await changeStream.next();
     *     }
     *     throw e;
     * }
     * ```
     *
     * @example
     * In emitter mode, if the change stream goes `timeoutMS` without emitting a change event, it will
     * emit an error event that returns a MongoOperationTimeoutError, but will not close the change
     * stream unless the resume attempt fails. There is no need to re-establish change listeners as
     * this will automatically continue emitting change events once the resume attempt completes.
     *
     * ```ts
     * const changeStream = collection.watch([], { timeoutMS: 100 });
     * changeStream.on('change', console.log);
     * changeStream.on('error', e => {
     *     if (e instanceof MongoOperationTimeoutError && !changeStream.closed) {
     *         // do nothing
     *     } else {
     *         changeStream.close();
     *     }
     * });
