Specific Staff Shortcode

I've gone withh creating a small plugin for this (all reviews)

<?php
/*
Plugin Name: Staff Reviews
Description: Displays staff reviews in a grid layout with star ratings.
Version: 1.0
Author: Name
*/

// Prevent direct access
if (!defined('ABSPATH')) {
    exit;
}

// Define constants
define('STAFF_REVIEWS_LIMIT', 25); // Number of reviews to display
define('STAFF_REVIEWS_TABLE', 'bookingpress_staff_review'); // Database table name

// Enqueue CSS
function staff_reviews_enqueue_styles() {
    wp_enqueue_style(
        'staff-reviews-css',
        plugin_dir_url(__FILE__) . 'assets/css/staff-reviews.css',
        array(), // No dependencies
        filemtime(plugin_dir_path(__FILE__) . 'assets/css/staff-reviews.css') // Version based on file modification time
    );
}
add_action('wp_enqueue_scripts', 'staff_reviews_enqueue_styles');

// Shortcode function
function staff_reviews_shortcode() {
    global $wpdb;

    // Fetch reviews
    $table_name = $wpdb->prefix . STAFF_REVIEWS_TABLE;
    $reviews = $wpdb->get_results($wpdb->prepare("
        SELECT bookingpress_customer_name, review_rating, review_title, review_comment, updated_at
        FROM $table_name
        ORDER BY updated_at DESC
        LIMIT %d
    ", STAFF_REVIEWS_LIMIT));

    // Error handling
    if (is_wp_error($reviews)) {
        return '<p class="staff-reviews-error">Грешка при зареждане на ревюта.</p>';
    }

    if (empty($reviews)) {
        return '<p class="staff-reviews-notice">Няма налични ревюта.</p>';
    }

    // Build output
    $output = '<div class="staff-reviews-grid">';
    foreach ($reviews as $review) {
        $output .= '<div class="staff-review-card">';
        $output .= '<div class="staff-review-header">';
        $output .= '<h3 class="staff-review-author">' . esc_html($review->bookingpress_customer_name) . '</h3>';
        $output .= '<div class="staff-star-rating">';

        // Generate star rating
        $rating = intval($review->review_rating);
        for ($i = 1; $i <= 5; $i++) {
            $output .= $i <= $rating
                ? '<span class="staff-star filled">★</span>'
                : '<span class="staff-star">☆</span>';
        }

        $output .= '</div></div>'; // Close star rating and header
        $output .= '<h4 class="staff-review-title">' . esc_html($review->review_title) . '</h4>';
        $output .= '<p class="staff-review-comment">' . esc_html($review->review_comment) . '</p>';
        $output .= '<time class="staff-review-date">' . esc_html(date('j/m/Y', strtotime($review->updated_at))) . '</time>';
        $output .= '</div>'; // Close review card
    }
    $output .= '</div>'; // Close grid

    return $output;
}
add_shortcode('staff_reviews', 'staff_reviews_shortcode');

It's very needed for services like therapy that the therapist doesn't change through the process.
