Changing the Post Title/Slug after front-end submissions based on fields

Hi,

I have a function changing the post title and slug after saving a post. It works fine in the editor, but I would like to make it work in front-end submissions. The function is:

add_action( 'rwmb_cat-and-dog-fields_after_save_post', 'update_cats_post_title');
		   
function update_cats_post_title( $post_id ) {

if ( 'cats' == get_post_type() ) {	

    $animals_name = rwmb_meta( 'animals_name', '', $post_id );
    $name_sequence = rwmb_meta( 'name_sequence', '', $post_id );
    $author_id = get_post_field( 'post_author', $post_id );
    $nickname = get_the_author_meta( 'display_name', $author_id );

    $post_slug = sanitize_title_with_dashes ($my_post,'','save');
    $post_slugsan = sanitize_title($post_slug);
    
    $my_post = array(
        'ID' => $post_id,
        'post_title' => $nickname . ' - Cat - ' . $animals_name . ' ' . $name_sequence ,
	'post_name' => $post_slugsan,
		
    );

    wp_update_post ( $my_post ) ;}
		
 }

I know in front-end submission I must use 'rwmb_frontend_after_save_post', but I don't know how to make it work with the above function, my attempts to integrate them failed. I will greatly appreciate your assistance.

Greetings,
Tom
