[Resolved] Dynamic create new post in the translated lang after adding post in main lang

I'm import data from a 3rd party system using API.
for each item i import, i create new post in the main Hebrew language and populate it with ACF data. i have also the data in English ready in vars in my script, but i don't know how to create also the English version of the same post.

I'm using a custom post "movies".

here is the part that i check if the post exists
$moviePost = get_page_by_title( $postTitle, OBJECT, 'movies' );
if ( $moviePost == null ) {
$post_id = wp_insert_post( $post );
} else {
// don't create new post
$post_id = $moviePost->ID;
}

and here the part where i update the post data:
update_post_meta( $post_id, '_visibility', 'visible' );
update_post_meta( $post_id, 'lang', $langHeb );
update_post_meta( $post_id, 'category', $category );
update_post_meta( $post_id, 'year', $year );
update_post_meta( $post_id, 'country', $countryHeb );
update_post_meta( $post_id, 'duration', $duration );
update_post_meta( $post_id, 'program', $programHeb );
wp_set_post_terms( $post_id, $tag, 'competition', true);
