如何输入在typescript中自动创建的Mongo字段？

import mongoose, { Schema, Document } from 'mongoose';

// 定义接口描述MongoDB文档结构
interface IUser extends Document {
  name: string;
  age: number;
  email: string;
}

// 创建用户模型
const UserSchema: Schema = new Schema({
  name: { type: String, required: true },
  age: { type: Number, required: true },
  email: { type: String, required: true }
});

const UserModel = mongoose.model<IUser>('User', UserSchema);

// 创建用户
const user: IUser = new UserModel({
  name: 'John',
  age: 25,
  email: 'john@example.com'
});

// 保存用户到数据库
user.save()
  .then((result) => {
    console.log('User created:', result);
  })
  .catch((error) => {
    console.error('Error creating user:', error);
  });
