Authorization expired, try removing the giftcard, and add it again

[PhuMinhPham]

Creating a customer payment connector and authorizing a payment and waiting more than 4 minutes to conclude the transaction, I'm getting this error message
The core payment sdk has reported the following errors while executing Microsoft.Dynamics.Retail.PaymentSDK.Portable.Response. Platform: Portable. Errors: code: AuthorizationFailure message: Authorization expired, try removing the giftcard, and add it again islocalized: True

Does anyone know what this means or how I can extend the expiration time?

Scenario:
A customer walks into the store with 3 gift cards.
The customer pays for the items with all 3 gift cards.
The gift card payment connector is a custom payment connector that withdraws the money from the card during authorization.
The customer still has an amount to pay and pays with a credit card of the remaining balance.
When the capture method kicks in, the authorization expiration error appears and stops the process from concluding.

According to the guide lines on how to create a custome payment connector, no such info about extending the authorization token is mention: https://learn.microsoft.com/en-us/dynamics365/commerce/dev-itpro/deploy-payment-connector#additional-resources
