How to include parent model data inside child model fetch in sequelize

Question

I have a models listed as in below:

const sequelize =require ('./db')

const UserInfo = sequelize.define('user',{
    userId : {type: DataTypes.INTEGER, primaryKey: true, allowNull: false},
    email: {type: DataTypes.STRING, unique: true, allowNull: false},
    password: {type: DataTypes.STRING, allowNull: false}
})
const User = sequelize.define('user_info',{
    id : {type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true, allowNull: false},
    userName : {type: DataTypes.STRING, unique: true, allowNull: false}
})

User.hasOne(UserInfo)
UserInfo.belongsTo(User)

module.exports = {User, UserInfo}

and I want to fetch UserInfo data so that I can get data from his parental model (User) as well, especially userName

    async login (req, res) {
        let {email, password} = req.body
        
        const user = await UserInfo.findOne({
            where: {email, password},
            include: [{model: User, as : 'user'}],
        })
        return res.json(user)
    }

So the result should look like this:

{
   email: 'someemail@gmail.com',
   password: 'somepassword', //(this data is listed in child UserInfo model)
   userName: 'user1234' //(this data is listed in parental User model)
}
