Looks good.

I think this was in one of the other PRs we didn't have time to merge before token transfers were enabled.

I'll add to regression tests for account_multisig.test.js today.

Which of them? This one https://github.com/near/near-api-js/pull/445/files doesn't seem to touch getKey method.

Yeah, I think we need to get full coverage for account_multisig.

Main problem I guess is that we didn't really use apps before Berry Club 🥑

Tested recoveryMethods in wallet linked to this branch. Looks like things are working.

The addKey override was likely left over from when everything was in wallet twoFactor.js.

Everything that's wallet specific, e.g. adding recovery methods, is handled now in wallet.js > addAccessKey but we may want to clean this up in the future.
