Is it possible to specify an HTTP method in a Spark notification?

I'm using Spark notifications as documented here:

https://spark.laravel.com/docs/4.0/notifications

Here's my code block to create the notification:

            $this->notifications->create($post->user, [
                'icon' => 'fa-exclamation-triangle',
                'body' => "My message to the user here",
                'action_text' => 'Reactivate Post',
                'action_url' => '/posts/' . $post->id . '/reactivate',
            ]);

Here's my route:

Route::post('/posts/{post}/reactivate', 'PostsController@reactivate')->where('post', '[0-9]+')->middleware('postToReactivateValid');

I'm getting a "MethodNotAllowedHttpException". This is because the action_url link is sending the request with a GET http method and my route accepts a POST http method.

Is there anywhere in creating the Spark notification to specify the HTTP method to use?
