BBMS Checkout Transaction token lifetime and retrievability

Hello can anyone confirm what's the BBMS Checkout (authorization) transaction token lifetime and whether it's possible to retrieve it via RE Merchant Services portal or any other portal?

We had a situation where the form submission which includes BBMS Checkout token was rejected due to recaptcha validation. The payment was approved but Checkout transaction endpoint was not called to collect the payment.

Now we wonder whether we can retrieve the checkout token and call the checkout transaction endpoint. We can see a transaction in RE Merchant Services Transaction List but the checkout token/transaction id is missing.

Any advise would be highly appreciated.

Cheers
