Classic editor implementation

Hello Jose.
This plugin seems to be what I’m looking for. But it will need some tweaking to work with my setup.

I use classic editor.

When I copy a YouTube link on it, it’s automatically picked up and embedded. This is seen on both back end editor and front end.

I would need to first have a function/snippet that completely disable this feature. No longer loading any of the assets WP uses for embedding.
(Maybe your plugin already does this?)

Second, I would need a code snippet to automatically add your short code to all YouTube links in the content. So I don’t have to manually type it every time. It will also take care of old links. Something like this:

function modify_youtube_links($content) {
    
    $pattern = '/https:\/\/www\.youtube\.com\/watch\?v=([a-zA-Z0-9_-]+)/';
    
    $replacement = '<p>[load_video_on_click link="https://www.youtube.com/watch?v=$1"]</p>';
    
    $content = preg_replace_callback($pattern, function($matches) use ($replacement) {
        return preg_replace('/\$1/', $matches[1], $replacement);
    }, $content);

    return $content;
}

add_filter('the_content', 'modify_youtube_links');

I hope to hear from you to see if I’m in the right track and what’s your opinion on this.
