I do see the derived Bitcoin addresses with their corresponding private keys on the far right side, what do I do with them?
Regarding the Bitcoin address I used, the addresses are showing on my live app so they are noted
Some wallets allow you to import individual addresses and private keys (like Electrum for example), so you dont even need a 24-word mnemonic backup in that case. In Electrum, run the Create new wallet wizard and select "Import Bitcoin Addresses or Private keys".
Be careful when copying and pasting private keys, and make sure your devices are secure and protected. Anyone with access to your private keys will have unrestricted access to your funds as well.
