The problem with randomizing posts

Hello. I am working on a project for my client 
This listing website uses WordPress, Elementor, Essential Addons for Elementor - Pro

With Essential Addons for Elementor - Pro, similar pages are displayed on pages using post grid (pages have categories), and similar pages are displayed on listing pages using Essential Addons for Elementor - Pro and "Posts Carousel" and "Post Block". The problem is that Posts Carousel, Post Block, Post grid display the same pages, but randomize only their order. I need the Posts Carousel, Post Block, Post grid widgets on Elementor pages to display randomized posts with a similar category as the current post (page or listing). When the page refreshes, this list should change. I came up with a way to double randomize. If I need to display 4 posts in a Post grid on an elementor page, first, 10 pages with the same category as the current page are randomly selected. After that, 4 pages are randomly selected from them. Here is the code for this function random_related_pages() {
global $post;
// Get the current page categories
$current_page_categories = wp_get_post_terms($post->ID, 'category', array("fields" => "ids"));

// Create a query
$args = array(
'post_type' => 'page',
'tax_query' => array(
array(
'taxonomy' => 'category',
'terms' => $current_page_categories,
),
),
'posts_per_page' => 10, // first, get 10 random pages
'orderby' => 'rand',
);
$random_pages_query = new WP_Query($args);

$output = '';
if ($random_pages_query->have_posts()) {
// Get all 10 pages in an array
$all_pages = array();
while ($random_pages_query->have_posts()) {
$random_pages_query->the_post();
$all_pages[] = '

' . get_the_title() . '

';
}

// Randomly pick 4 from the array
$picked_pages = array_rand($all_pages, 4);

// Output the picked pages
foreach ($picked_pages as $index) {
$output .= $all_pages[$index];
}
} else {
// No pages found
}
wp_reset_postdata();

return $output;
}
add_shortcode('random_related_pages', 'random_related_pages');
but I need it to change the list of posts for the Posts Carousel, Post Block, Post grid from the Essential Addons for Elementor plugin (these widgets already have a certain design). What can I do? How can I set up a real randomization for these blocks?
