Lesson 10: Why do we need to parse tx in the handleNewNotification() function while it has no parameter at all

[ghost]

const handleSuccess = async (tx) => {
        await tx.wait(1)
        handleNewNotification(tx)
    }
    const handleNewNotification= () => {
        dispatch({
            type: "info",
            message: "Transaction Complete!",
            title: "Tx Notification",
            position: "topR",
            icon: "metamask"
        })
    }

I'm quite confusing why do we need to parse tx to handleNewNotification(tx). I have tried not to parse the tx as argument and the code work just fine. Can someone explain to me please .

@Sotatek-DuongPhan It is optional, if you want information about your transaction in the Notification (frontend) then you need to pass it here and get the info from it.
