        The session cookie created by Odoo has not the attribute SameSite. Most of browsers will force this attribute
        with the value 'Lax'. After the payment, Sips will perform a POST request on this route. For all these reasons,
        the cookie won't be added to the request. As a result, if we want to save the session, the server will create
        a new session cookie. Therefore, the previous session and all related information will be lost, so it will lead
        to undesirable behaviors. This is the reason why `save_session=False` is needed.
