Enagble laravel-debugbar at runtime

I want to enable laravel-debugbar at runtime, as you can see here (from my middleware):

        Config::set('app.debug', true);
        config(['app.debug' => true, 'debugbar.enabled' => true]);

        \DebugBar::enable();

        DebugBar::enable();

        (new LaravelDebugbar())->enable();

        $provider = new ServiceProvider(app());
        $provider->register();
        $provider->boot();

I have tried a lot of options, and all have failed, I've also tried adding it to my AppServiceProvider:

$this->app->register(\Barryvdh\Debugbar\ServiceProvider::class);

But I just cannot seem to dynamically make the debug bar load when I want to it.

How can I?
