     * By using an intersection we can save time and ensure defaults remain the same type!
     * ```ts
     * collection

     *     { $addFields: { comment: 'big changes' } },
     *     { $match: { operationType: 'insert' } }
     *   ])
     *   .on('change', change => {
     *     change.comment.startsWith('big');
     *     change.operationType === 'insert';
     *     // No need to narrow in code because the generics did that for us!
     *     expectType<Schema>(change.fullDocument);
     *   });
