Wraps Stytch's Exchange Session endpoint and exchanges the member's current session for a session in the specified Organization.
If this method succeeds and the Member is not required to complete MFA, the Member will be logged in, granted an active session, and the session cookies will be minted and stored in the browser.
If this method succeeds and MFA is required, the intermediate session token will be stored in the browser as a cookie.
You can listen for successful login events anywhere in the codebase with the stytch.session.onChange() method or useStytchMemberSession hook if you are using React.
