     * watch() accepts two generic arguments for distinct usecases:
     * - The first is to override the schema that may be defined for this specific collection
     * - 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
     * @example
     * By just providing the first argument I can type the change to be `ChangeStreamDocument<{ _id: number }>`
     * ```ts
     * collection.watch<{ _id: number }>()
     *   .on('change', change => console.log(change._id.toFixed(4)));
     * ```
     *
     * @example
     * Passing a second argument provides a way to reflect the type changes caused by an advanced pipeline.
     * Here, we are using a pipeline to have MongoDB filter for insert changes only and add a comment.
     * No need start from scratch on the ChangeStreamInsertDocument type!
     * By using an intersection we can save time and ensure defaults remain the same type!
     * ```ts
     * collection

     *     { $addFields: { comment: 'big changes' } },
