Agree that google pay is becoming popular now. I got a few error messages "OSCLASS PAY - STRIPE CANCEL DEBUG RESPONSE" when users trying to pay via g-pay.

Please add a gateway for Kazakhstan.
PayBox: https://paybox.money/
CloudPayments: https://cloudpayments.kz/
Or you can expand YandexMoney (YooKassa) for Kazakhstan, now it works only for Russia: https://yookassa.ru/

Each has English documentation.
