Get tag title and replace number of posts for tag cloud

I need to list a cloud of tags but need to replace standard link title with tag title. Tag title is stored as custom field using ACF plugin (field name is ‘title_page’). I’m looking for the way which will not create high load on site. Current so

$args = array(
'smallest' => 10,
'largest' => 10,
'number' => 250,
'topic_count_text_callback' => 'my_tag_text_callback',
); 
wp_tag_cloud( $args );  

Where my_tag_text_callback function is described in functions.php:

function my_tag_text_callback( $term_id ) {
$queried_object = get_queried_object();
$term_id = $queried_object->term_id;  
$key_title = get_field("title_page", $term_id);
return $key_title;
}

Unfortunately last piece of code does not give any result.
