Adding domains insted of parking them

I have bought a domain and want to use it instead of the 000webhostapp domain that I tested the site with. how can I do that, since I don’t see an option for Add-ons but only am ale to park the domain, which is not what I want to do

As far as i know…this is only way to park or point domain.

You point your domain using the new control panel and your content will resolve to yoursite.com
