I want to send transactions using ts-sdk + ledger.

What error, if any, are you getting?

No response

What have you tried or looked at? Or how can we reproduce the error?

If i understand correctly, we're supposed to use this method static fromDerivationPath(path: string, mnemonics: string): Ed25519PrivateKey.

However, this requires typing in mnemonics according to the README example below, which looks risky.

const path = "m/44'/637'/0'/0'/1";
const mnemonic = "various float stumble...";
const account = Account.fromDerivationPath({ path, mnemonic });

I wonder what's the recommended way of doing it such that users don't have to input the sensitive mnomonic?

Which operating system are you using?

macOS

Which SDK or tool are you using? (if any)
