How to change payment methods by hook in woocommerce cart?

Question

WordPress

Please tell me what is wrong

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );
add_filter( 'woocommerce_available_payment_gateways' , 'unsetting_payment_gateway', 10, 1);

function wc_minimum_order_amount() {
  $limit_reached = false;
  // Задать переменную, чтобы указать минимальное значение заказа
  $minimum = 1000;	
    if ( WC()->cart->total < $minimum ) {
      function unsetting_payment_gateway( $available_gateways ) {
        // Здесь установить способ оплаты
        unset($available_gateways['cod']);
      }
    }
    return $available_gateways;
}

Required if the order amount is less than 1000, make the payment method "Pay on delivery" inactive or do not show
Thank you in advance

Working code:

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

$limit_reached = false;

function wc_minimum_order_amount() 
{
  // Задать переменную, чтобы указать минимальное значение заказа
  $minimum = 1000;
  
  if ( WC()->cart->total < $minimum ) {
    $limit_reached = true;
    
  }
  return $limit_reached;
}

function unsetting_payment_gateways( $available_gateways ) 
{	
  $limit_reached = wc_minimum_order_amount();
  if ($limit_reached) {			
      // Здесь установить способ оплаты
      unset($available_gateways['cod']);
  }
  
  return $available_gateways;
}
add_action('woocommerce_available_payment_gateways', 'unsetting_payment_gateways');
