Laravel: Pass User's Notifications to All Members of Route Group

I have a route group defined like so:

Route::group(['middleware' => 'auth'], function(){

  Route::get('/app', function () {
      //return the view...
  });
  Route::get('/calc', function () {
      //return the view...
  });
  Route::get('/fries', function () {
      //return the view...
  });

});

And I want to be able to pass in the user's notifications to all of these views with something like:

Notifications::all()->where('for', '=', Auth::user()->id);

I'm using Laravel 5.4, and I can't find any info for this online surprisingly. I have only come across ViewServiceProviders which I dont think is what I'm looking for.

Is it as simple as adding ->with(...) to the end of my route group?

Thanks!
