Thanks to the developers

Here is the code I wrote for discord, you can use it:

<?php
/*
 * Plugin Name: Post to Discord
 * Plugin URI: https://win-win-trade.com/
 * Description: Announces new WordPress posts on Discord.
 * Version: 1.0
 * Author: Win-win Trade
 * Author URI: https://win-win-trade.com/
*/

    if (get_option('discord_webhook_url') == null) 
        return;
      
    if ($new_status != 'publish' || $old_status == 'publish' || $post->post_type != 'post')
        return;
 
    $webhookURL = get_option('discord_webhook_url');
    $id = $post->ID;
 
    $author = $post->post_author;
    $authorName = get_the_author_meta('display_name', $author);
    $postTitle = $post->post_title;
    $permalink = get_permalink($id);
    $excerpt = $post->post_excerpt;

    // Get the featured image URL
    $featuredImage = get_the_post_thumbnail_url($post, 'full');
 
    // Create the payload for the message
    $payload = array(
        'content' => "@everyone " . $authorName . " just posted \"" . $postTitle . "\" - " . $permalink . "",
        'embeds' => array(
            array(

                ),
                'description' => $excerpt
