My fields are as follows: authors is a group field and within that I have a subfield of people (amongst other subfields). People is a multiple post_object select field.

I have the impression from this thread that it is possible to query subfields in this way…

$images_query = new WP_Query([
    'posts_per_page' => -1,
    'post_type' => 'images',
    'meta_query' => [
        [
            'key' => 'authors_%_people',
            'value' => ['85'],
            'compare' => 'IN'
        ],
    ],
]);

It is not working, please could you advise me.
