How do we properly code the below?
I am looking to have auto-applied coupon in cart for mix-match products and minimum quantity should be 5 but can’t figure it out. I already created a coupon based on specific ID but just want to apply another function for minimum quantity in cart. Thanks

// Hook into the "woocommerce_before_calculate_totals" action
add_action('woocommerce_before_calculate_totals', 'woosuite_apply_coupon_based_on_product_count');

function woosuite_apply_coupon_based_on_product_count() {
    $coupon_code = 'Mix Match Bundles'; // coupon code id
    $minimum_product_count = 4; // Minimum product count to apply the coupon

    $product_count = WC()->cart->get_cart_contents_count();

    
     if ($product_count <= $minimum_product_count) {
       if (WC()->cart->has_discount($coupon_code)) {
            return; // Coupon is already applied
        }
        // remove coupon 
        WC()->cart->remove_coupon($coupon_code);
    }
}
