Glad that you were able to find a solution. If you’ll need to include other pages, then you can try doing it as such:
add_action( 'enqueue_block_editor_assets', function() {
if(get_the_ID() == 13508 || get_the_ID() == 13509){
wp_enqueue_style( 'my-block-editor-styles', get_stylesheet_directory_uri() . "/editor-style.css", false,'1.0', 'all' );
}
} );
The || operator denotes an OR logical operator. In short the code above say if the ID of the page is 13508 OR 13509, then run the code. If you’ll have more, you can simply add more ||.
See this for reference: https://www.php.net/manual/en/language.operators.logical.php
Hope this clarifies! 🙂
