Laravel subdomain routing redirect to 404 if route not in subdomain

Question

I am using subdomain routing in my app and will like for requests to subdomain routes to be redirected to a 404 page if the requested route does not exists in the subdomain. Here is the scenario:

// Subdomain routes
Route::domain('app.mysite.test')->group(function(){
    Route::get('/', function(){
        dd("Home page for subdomain");
    });

    Route::get('/404', function(){
        dd("Subdomain 404");
    });
    //... other subdomain routes here
});

// Top domain routes
Route::group(['namespace' => 'Site'], function(){
    Route::get('/', function(){
        dd("Main site home page");
    });

    Route::get('/login', function(){
        dd("Main site LOGIN page");
    });
});

In the above scenario, if someone tries to access a route that does not exist in the subdomain (eg http://app.mysite.test/login), they will be automatically redirected to the login page of the main site (ie: http://mysite.test/login).

My question is: How to I redirect users to http://app.mysite.test/404 if they try to access http://app.mysite.test/login?

I think I found a solution: At the end of the Subddomain route group, add a catchall expression that basically catches everything that's not in the subdomain routes and renders the 404 page. Make sure this catchall route is at the end of your subdomain routes:

// Subdomain routes
Route::domain('app.mysite.test')->group(function(){
    Route::get('/', function(){
        dd("Home page for subdomain");
    });

    //Route::get('/404', function(){
    //    dd("Subdomain 404");
    //});
    //... other subdomain routes here

    // ADD THE CATCHALL REGEX HERE
    Route::get("{catchall}", function(){
        dd("404 page from subdomain");
    })->where('catchall', '(.*)');
});

// Top domain routes
Route::group(['namespace' => 'Site'], function(){
    Route::get('/', function(){
        dd("Main site home page");
    });

    Route::get('/login', function(){
        dd("Main site LOGIN page");
    });
});
