I have a field group with ID group_61318c077c7d6.

In that group is a field with ID field_61318c078a746, a relationship field.

I’d like to create a Gutenberg slider block like this one, which loops over the rows of group_61318c077c7d6 and grabs the featured image of the field_61318c078a746’s related post.

So, something like:

<div id="<?php echo esc_attr($id); ?>" class="<?php echo esc_attr($className); ?>">
<?php if( have_rows('group_61318c077c7d6') ): ?>
<div class="slides">
<?php while( have_rows('group_61318c077c7d6') ): the_row();
$template = get_field('field_61318c078a746');
if ( $template ) : $image = // get the template's thumbnail
?>
<div>
<?php echo wp_get_attachment_image( $image['id'], 'full' ); ?>
</div>
<?php endwhile; ?>
</div>
<?php else: ?>
<p>Please add some slides.</p>
<?php endif; ?>
</div>

How do I complete this code to grab the featured image of the field_61318c078a746’s related post, please?

Help appreciated.
