If you search (via threadloom) for Flight Credit Wallet, you'll find a result for an actual thread:
AA introduces Flight Credit Wallet (Aug 2020)

But if you click on the search result, you get a broken link error.

The same link is posted here in the Wiki:
GUIDE to Trip Credit, Flight Credit, Travel Voucher, Gift Card, Refund

And it also reports as broken.

"Invalid Thread specified. If you followed a valid link, please notify the administrator

Any idea why the entire thread is no longer accessible?
