Execute the following commands:

symfony console importmap:require bootstrap
symfony console importmap:require bootstrap/dist/css/bootstrap.min.css

This adds the bootstrap packages to your importmap.php file:

// importmap.php
return [
    'app' => [
        'path' => './assets/app.js',
        'entrypoint' => true,
    ],
    'bootstrap' => [
        'version' => '5.3.0',
    ],
    'bootstrap/dist/css/bootstrap.min.css' => [
        'version' => '5.3.3',
        'type' => 'css',
    ],
];

Then, import those files:

// assets/app.js
import 'bootstrap';
import 'bootstrap/dist/css/bootstrap.min.css';
