I had created a custom module to update order state and payment state. In my controller i used the following code to change the order state of order.

 $order = \Drupal\commerce_order\Entity\Order::load($order_id);
      if($payment_status === 'payment.captured' ){
        $order->set('state', 'completed' );
        $order->save();
      }
      else{
        $order->set('state', 'pending' );
        $order->save();
      }
      
     }

Similarly how can i change the payment state of a payment which comes inside that order.

 else {

   $order->save();
 }
      

How can I now change the payment state of a payment which comes inside that order?

This is the screenshot of my payment. Now the payment state is pending. I want to change it to something else by using code, for example completed.
