This is something you must try yourself.
On your server, find and edit this file:
wp-content/plugins/elementor/includes/template-library/sources/local.php
from line 110 onwards find this code:
public function get_items( $args = [] ) {
$templates_query = new \WP_Query(
[
'post_type' => self::CPT,
'post_status' => 'publish',
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'ASC',
'meta_query' => [
[
'key' => self::TYPE_META_KEY,
'value' => self::$_template_types,
],
],
]
);
Try by adding one new/extra line, after this line:
'order' => 'ASC',
As this:
'search_filter_id' => '4330',
and see if that works?
