Events in Laravel: Best Practice

Hello :) I think about using laravel events like this, because it seems for me a bit easier to read.

// Load event/listener
$dispatcher->listen('track.gtm.visit', TrackGTM::class);

// Later in code
event('track.gtm.visit');

I have a few questions about this:

1. Do you think this is a good idea, or should I go with the default solution to make it more readable for other developers? Because for me it feels, that this is more readable, because I have less files in my system.

2. Is there a way to put methods behind class like this:

$dispatcher->listen('track.gtm.visit', (new TrackGTM())->doIt());

Because this everytime triggers the doIt function and not only when I do the event() helper function with the event.
