how to set trusted proxies for laravel 5.5

Quoting https://laravel-news.com/trusted-proxy

You can create the config/trustedproxy.php configuration by running vendor:publish:

php artisan vendor:publish --provider="Fideloper\Proxy\TrustedProxyServiceProvider"

I did that and altho it said "Publishing complete." I'm not seeing a config/trustedproxy.php file...

I did grep -r Fideloper . and that did not return any results either...

I'm running Laravel 5.5
