What happened?

Got roughly this error reported from users, and I can replicate. If you have expert mode off on the cosmos ledger app, you can't create keys with index > 100.

osmosisd keys add --ledger --index="102" test_102
Error: failed to generate ledger key: failed to recover pubkey: [APDU_CODE_CONDITIONS_NOT_SATISFIED] Conditions of use not satisfied: address rejected for path m/44'/118'/0'/0/102

We should make a more friendly error message in such cases, informing the user to enable expert mode.

Cosmos SDK Version

0.47

How to reproduce?

Connect a ledger. Open cosmos app, ensure expert mode is off. Run:

$DAEMON keys add --ledger --index="102" test_102

You will see:

Error: failed to generate ledger key: failed to recover pubkey: [APDU_CODE_CONDITIONS_NOT_SATISFIED] Conditions of use not satisfied: address rejected for path m/44'/118'/0'/0/102

Enable expert mode, it will work.

Normally, scanning balances occurs sequentially: 0, 1, 2, ... N. Please note that this process can be time-consuming. As part of a security measure, Expert mode is required to retrieve an {address, pubkey} with a large index (greater than 100). If a compromised wallet uses a high index and you are unaware of it, you (temporarily) might lose access to funds sent there.
