Custom Query Product Visibility

Hello your app is working fine. The products I filter by country are hidden on the shop page. I have a custom query on my front page. products are not filtered by country in that cycle.How do I add a filter by country in my custom query?

$args = array(
‘tax_query’ => array(
array(
‘taxonomy’ => ‘product_cat’,
‘field’ => ‘slug’,
‘terms’ => ‘clothing’
)
),
‘post_type’=>’product’,
‘order_by’=>’date’,
‘order’=>’DESC’,
‘posts_per_page’=>-4
);
