I have html files with specific tags under the views folder. I am using Twig for template processing and rendering.

My index.php:

<?php
include("lib/init.php");

echo $twig->render('index.html', $data);
?>

Question:

How can I tell Twig to load a specific html from the views folder and add it to the current index.html rendering?

I am unable to find anything in the documentation, I looked at blocks (https://twig.symfony.com/doc/2.x/functions/block.html).

Other details, composer.json:

{
    "config": {
        "platform": {
            "php": "8.3.9"
        }
    },
    "require": {
        "twig/twig": "^3.10",
        "spomky-labs/otphp": "^10.0"
    }
}
