Return 某些字段带有来自 Mongoose 的 populate()

Question

在我运行此查询查询后，我从 MongoDB 返回了一个 JSON 值。 replyID 是另一个 Schema User 的对象，它有 _id、email 和 user。但是 我不想要用户的电子邮件和 _id，只想要名字。 我应该向填充函数添加什么以仅获取名称？查询 ->

.populate({
    path: 'replies',
    populate: { path: 'replyID' }
})

JSON 返回

"comments": [
    {
        "_id": "6296fcda39d113539bbe023d",
        "creator": "62948aff05bcfdb5e75df7e6",

        ],
        "replies": [
