[SadeghShojayefard]

Hi I want create Persistent sessions in Next Auth.
I want when the user check remember me the session (maxAge) is set for 7 day.
but when the remember me not checked the session is expired after the browser is close.
how can dynamically manage this.
my project is next js 16/type script.
i write this code base on some solution in internet in session callback but is not working:

            if (!token.rememberMe) {
                session.expires = new Date(0).toISOString();
                session.maxAge = 0;

            } else {
                const expires = new Date(Date.now() + SEVEN_DAYS * 1000);
                session.expires = expires.toISOString();
                session.maxAge = Number(expires);
            }

how can fix this? please help
