chain static methods in mongoose doesn't work

I tried static methods in es6, any clue why I can't chain my static method like below? Is it even possible to chain 2 static methods?

//nameModel.js
const schema = new mongoose.Schema({ name: String })
class NameClass {
  static async findAll() {
    return this.find({})
  }
}
schema.loadClass(NameClass)
export const model = initModel('NameSchema', schema)

//controller.js
import { model as NameModel } from '../models/nameModel'
export default () => async (req, res) {
  try {


const test = await NameModel.findAll()
    console.log('test', test) //have all the records

    const response = await NameModel.findAll().sort('-name') // NameMode.sort is not a function
  } catch (e) {
    console.log(e)
  }
}

What is the diffrence between static and non static method in mongoose schema? I'm confused as the doc only show code sample. I felt it's redundant as it doesn't show difference between two http://mongoosejs.com/docs/advanced_schemas.html

this in static method is refer to class function itself, since it defined as a method of a class.

class NameClass {
  static async findAll() {
    return this.find({})
  }
}

is equal to:

class NameClass {}
NameClass.findAll = async function() {
  return this.find({})
}
