How to insert/update data in custom created table in hikashop payment plugin

-- HikaShop version -- : 4.3.0
-- Joomla version -- : 3.9.19
-- PHP version -- : 7.3

Hello,

I am working on custom third party payment plugin. I have created a new table "mmf9b_customer_saved_cards" using install script in my plugin. Now I want to save data into this table in onPaymentNotification function.

I saw that we can save data in order table like below :

$orderClass = hikashop_get('class.order');
$order = new stdClass();
$order->order_id = $order_id;
$order->custom_auth_number = $authNumber;
$order->custom_txn_id = $transactionId;
$orderClass->save($order);

But I don't know I how to save in my newly created table which is "mmf9b_customer_saved_cards".

So if anyone has knowledge about this then please let me know.

Thanks in advance!

Thanks for very helpful information.
