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 data will be persisted on device.
If this method succeeds and MFA is required, the intermediate session token will be persisted on device.
You can listen for successful login events anywhere in the codebase with the stytch.session.onChange() method or useStytchMemberSession hook.
