Laravel: Remove Request Throttling For Authenticated Users

I wish to disable request throttling for users that are authenticated through the API.

Kernel:

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],

    'api' => [
        'throttle:240,1'
    ],
];

Throttle here will limit the requests to 240 per minute regardless of whether or not a user is authenticated.

How would it be possible to do this so it only throttles unauthenticated users?
