怎么设定 mongoose schema 有 soft delete 和 _id 等于 id
最近想弄个博客，但发现在使用 mongoose 时 产生的 id 都会是 _id，而且没有 soft delete 的机制 想询问该怎么写 schema 才会有这些功能？

const mongoose = require("mongoose");
const {
Model,
Schema,

const userSchema = new Schema({
user_id: { type: String, default: '' },
github: { type: Object, default: {} },
groups: [
{ type: String, default: '' }
],
friends: [
{ type: String, default: '' }
],
status: { type: String, default: 'offline' },
});
class UserClass extends Model {
static async save(data) {
let Group = require('./Group.model')
let isGroupExist = await Group.find({})
!isGroupExist.length && await Group.create({

administratorList: [data.github.id],
memberList: [],
creator: [data.github.id],

await Group.join_member({

}
}
static async findOnePretty(data) {
