ES6 How to declare an instance of a class inside a function

This is my user.js function. How do I create an instance of it in another file? I understand that this structure is a function that contains a class that contains functions inside it.

user.js

'use strict';
const {Sequelize} = require('sequelize');
const {
  Model
} = require('sequelize');

//This is a function that contains a class that contains functions

module.exports = (sequelize, DataTypes) => {
  class User extends Model {
     static init(sequelize) {
        super.init(
        {
          name: Sequelize.STRING,
        },
        {
          sequelize,
        });
        this.addHook('beforeSave', async (user) => {
          return user.id = uuid();
        });
        return this;
      }
      static associate(models) {
        // define association here
        User.hasMany(UserRole,
          {
            foreignKey: {
              field:'UserId',
              allowNull: false,
            },
          });
      }
  }

  User.init({
    Id: DataTypes.UUID,
    Name: DataTypes.STRING,
    UserName: DataTypes.STRING,
    Email: DataTypes.STRING,
    Password: DataTypes.STRING,
    PhoneNumber: DataTypes.STRING,
    MobileNumber: DataTypes.STRING,
    DateOfBirth: DataTypes.DATE,
    LockoutEnabled: DataTypes.BOOLEAN,
    LockoutEnd: DataTypes.DATE
  }, {
    sequelize,
    modelName: 'User',
  });

  return User;
};

In another file I have tried:

const {Sequelize, DataTypes} = require('sequelize');
const {sequelize} = require('../../database/connect');
const {userModel} = require('../../models/user');


function GetAll(UserName, Email){
  var option = new userModel;
  var option2 = new userModel(sequelize, DataTypes);
  return "1";
}

But both give me this error:

TypeError: userModel is not a constructor

EDIT:

If I remove new from them, I get the error: userModel is not a function.
