WHY IT NEEDS A POLICY

Why create_qr needs a policy

It is part of a payment gateway server (Xendit) alongside tools like create_disbursement and create_ewallet_charge. Creating a QR code for payment commits a payment request and involves financial obligations, placing it firmly in the Financial category.
