Setting up an error message for minimum quantity in WooCommerce - wordpress

Question

I set up a minimum quantity for a product category in WooCommerce. In my case I set the minimum quantity to 5 items. The code I use works fine but I would like to add two error messages for the customer:
1) If the customer tries to change the the quantity to less than the minimum by clicking the "-" symbol I would like to have something like: "The minimum quantity of this product is 5, please add at least 5 items to the basket"
2) If the customer clicks the "add to the basket" button I would like to have something like this: "There is a minimum quantity of 5 items for this product. Please check your basket"
Is there some code I can add to my actual code?
add_filter( 'woocommerce_quantity_input_args', 'min_qty_filter_callback', 20, 2 );
function min_qty_filter_callback( $args, $product ) {
$category = 'Noten'; // The targeted product category
$min_qty = 5; // The minimum product quantity
$product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();
if( has_term( $category, 'product_cat', $product_id ) ){
$args['min_value'] = $min_qty;
}
return $args;
}

For add to cart validation add the follows code snippet to validate your item quantity -
function add_to_cart_validation( $flag, $product_id, $qunatity ) {
if( $qunatity < 5 ) { // if quantity less than 5
wc_add_notice( __( 'There is a minimum quantity of 5 items for this product. Please check your basket', 'text-domain' ), 'error' );
$flag = false;
}
return $flag;
}
add_filter( 'woocommerce_add_to_cart_validation', 'add_to_cart_validation', 10, 3 );
