Redirect Bank Payment customer to Order Complete page instead of Invoice

[kUdtiHaEX]

In WHMCS settings I've set to redirect customers directly to the Payment page after checkout. That works fine for PayPal or Credit Cards, however if someone selected a Bank Transfer, he is going to be redirected to the `viewinvoice.php`. 

I've hooked into `AfterShoppingCartCheckout`:

add_hook('AfterShoppingCartCheckout', 1, function($vars) {
    //Load configuration
    use WHMCS\Config\Setting;

    if ($vars['PaymentMethod'] === "banktransfer") {
        $redirect = Setting::getValue('SystemURL') . "/cart.php?a=complete";
        header("Location: $redirect");
    }
});

However, no matter what I do  it always redirects to `viewinvoice.php`. How can I resolve this?
