Using shield, How i can redirect to separate url if the user not in admin group

If I understand well, here is my solution to handle admin and portal namespaces.
Here is before method from my Admin filter:

PHP Code:

    public function before(RequestInterface $request, $arguments = null)
    {
        if (! $request instanceof IncomingRequest) {
            return;
        }

        if (auth()->user()->inGroup('superadmin', 'admin')) {
            return;
        }

        return redirect()->to('login');
    } 


And here is before method from my Portal filter:

PHP Code:

    public function before(RequestInterface $request, $arguments = null)
    {
        if (! $request instanceof IncomingRequest) {
            return;
        }

        if (auth()->user()->inGroup('customer')) {
            return;
        }

        return redirect()->to('login');
    } 


As you can see I'm using group customer for my portal users. 
Here is updated redirects, loginRedirect and registerRedirect methods in Shield auth config.

PHP Code:

    public array $redirects = [
        'register'    => 'portal',
        'login'      => 'portal',
        'logout'      => 'login',
        'force_reset' => '/',
    ]; 


PHP Code:

    public function loginRedirect(): string
    {
        $url = auth()->user()->inGroup('customer')
            ? setting('Auth.redirects')['login']
            : site_url(ADMIN_AREA);

        return $this->getUrl($url);
    } 


PHP Code:

    public function registerRedirect(): string
    {
        $url = auth()->user()->inGroup('customer')
            ? setting('Auth.redirects')['register']
            : site_url(ADMIN_AREA);

        return $this->getUrl($url);
    }
