How to update the state from previous case study

UpdateState.tsx

    const update = () => {
        // can not be within 5 seconds of each other.
        if (account.getLastUpdate() - new Date().getTime() < 5000) {
            return;
        }

        // update account then reset the state so it updates!
        account.update().then((returnedScope: any) => {
            let currentTime = new Date().getTime();
            setAccount(returnedScope); // update account data!
        });
    }
