Get terms only if has posts of post type?

1

Is this possible?

I have a global taxonomy ‘brands’, I have set up for products cpt and resources cpt.
On a page, I want to show all brands that have posts from the resources cpt.

I tried with a query loop, and nested another but couldn’t figure it out.

I need this because, some brands have products but not resources and vice-versa

Got it with query editor:
Claude for the rescue!

// Get all wpdmpro post IDs first
$wpdmpro_posts = get_posts([
    'post_type' => 'wpdmpro',
    'numberposts' => -1,
    'fields' => 'ids'
]);

// If no wpdmpro posts exist, return empty result
if (empty($wpdmpro_posts)) {
    return [
        'taxonomy' => 'marca',
        'include' => [0], // This will return no terms
    ];
}

// Return query for marca terms that have wpdmpro posts
return [
    'taxonomy' => 'marca',
    'hide_empty' => true,
    'object_ids' => $wpdmpro_posts
];
