I want to do full customization of jitsi meet UI

Hi, I want to do full customization of jitsi meet UI using react, how should I proceed, should I need to do server setup using this guide [How to] How to build Jitsi Meet from source: A developer’s guide and make changes directly in the source (there are lot of changes I need to do) or should I use lib jitsi meet api’s in my own react project, I don’t have a domain name can I use my private IP address for local development. which path should I take.
