How to use the trezor-connect.default.ethereumSignTransaction function in trezor-connect

    TrezorConnect.ethereumSignTransaction({ device: this.device, path, transaction }).then(res => {
      if (!res.success) return cb(new Error(res.payload.error))
      cb(null, res.payload)
    }).catch(err => cb(err))
  }
