Old Brave Wallet backup

Hello dear support, please advise.

Description of the issue:

Couple of years ago, I’ve been using earlier versions of Brave for Windows, with built-in wallet web3 extenstion (default, not Metamask)

I got backup dir with MANIFEST-000001, and *.ldb files.
How can I arrange to load this backup in recent Brave versions?

There is no *.ldb files
c:\Users\{my user}\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default\
in recent versions, so I don’t know were to copy my back to load it**

Operating System and Brave Version(See the About Brave page in the main menu):**

Latest Brave 1.83.50 Windows

Hello - You must have the recovery phrase or private key to restore the wallet and address. You can learn more here: https://support.brave.app/hc/en-us/articles/16291144373261-What-is-a-Recovery-Phrase

Thanks!

I don’t have recovery phrase( Only backup files, which usually worked for extensions.

Brave Wallet is a secure, encrypted self-custody wallet. Unfortunately, backing up the wallet does not work in the same way as other extensions. Encrypted self-custody wallets rely on the BIP-39 recovery phrase for generating a secure backup.
