I am facing an issue in my Node.js app, where the log says "Invalid shorthand initializer". However, I checked online, and the official syntax to declare super constructor objects, is by doing objectname = {property: 'X'};
However, for the options = { line, it gives me this error message.
What am I doing wrong here? How is options declared correctly?

const { Sequelize } = require("sequelize");

module.exports = class Database extends Sequelize {
    constructor() {
        super({
            database : process.env.DatabaseName,
            username : process.env.DatabaseUsername,
            password : process.env.DatabasePassword,
            options = {
                host: process.env.DatabaseHost,
                dialect: "mysql"
            }
        })
    };

    Authenticate() {
        this
            .authenticate()
            .then(() => console.log(`Logged in to Database ${process.env.DatabaseName}!`))
            .catch(err => console.log(err));
    };
};

My dependencies in the package.json:
