How to apply theme in Laravel-inertia-react?

Hi guys, I tried to study Laravel 9 with breeze-inertia-react but I can't configure out how to apply theme in this set-up since it's a JS components.

this is the app.blade.php

<body class="font-sans antialiased">
        @inertia

        @env ('local')
            <script src="http://localhost:8080/js/bundle.js"></script>
        @endenv
    </body>

How do I change the structure and include nav, header, footer? I can't see videos in YouTube.
