Serving a "Test" site

My client's website is currently in Wordpress and located in public. I have built a new site for them in Laravel and need to show them the new site before replacing the Wordpress site. I've uploaded all of the Laravel files and named the Laravel public directory to public2 so that it doesn't conflict with the WP site.

.env
app
bootstrap
database
public <-- current live WP site
public2 <-- laravel "public" dir
resources
etc...

With a static HTML site I could just point my client to http://site.com/public2 and they'd be able to preview it. How would I go about showing them the Laravel site?
