如何在typescript中输入mongoose ObjectID数组

npm install mongoose
npm install --save-dev @types/mongoose
npm install --save-dev typescript

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

interface User extends Document {
  name: string;
  friends: Types.ObjectId[];
}

const userSchema: Schema = new Schema({
  name: { type: String, required: true },
  friends: [{ type: Schema.Types.ObjectId, ref: 'User' }]
});

const User = mongoose.model<User>('User', userSchema);
export default User;

const newUser: User = new User({
  name: 'John Doe',
  friends: [new Types.ObjectId(), new Types.ObjectId()]
});

const friendId: Types.ObjectId = new Types.ObjectId();
const usersWithFriend: User[] = await User.find({ friends: friendId });
