Is it possible to request a cancellation for my IMT (International Money Transfer) transaction?

If a customer uses the 'credit to account' delivery method when making an international money transfer (IMT), they can cancel the transaction while the payment status is still 'payable'.
However, if the customer chooses the PIX payment method, cancellation is not possible due to the rapid processing speed of PIX payments.
