some options don't work

[PoBiRi]

'clearExpired', 'checkExpirationInterval', 'expiration' options don't works in my code how can i fixed it? it seems to need some privileges, what privileges need for these options?

const mysql = require('mysql');

const db = mysql.createConnection({
    host: 'localhost',
    user: 'host',
    password: '1234',
    database: 'pohub',
    port:'3306'
});

const sessionStore = new MySQLStore({
    clearExpired: true,
    checkExpirationInterval: 5000,
    expiration: 10000,
}, db);

app.use(
    session({
        httpOnly: true,
        secret: "hello",
        resave: false,
        saveUninitialized: false,
        store: sessionStore,
        cookie: {
            maxAge: 10000,
            sameSite: 'lax',
            /*secure: true,
            sameSite: 'none',*/
        }
    })
);

How do you know these options don't work? What have you tried? What have you observed? What errors, if any, do you see in your logs?

when make session with this user account, data record doesn't disappear in my mysql database. but with my root account, there is no problem.
