basic approach with

// somewhere in index.ts
if (config.createServiceAccount) {
  const serviceAccount = new ...
  const serviceAccountKey = new ...
  export const serviceAccountPrivateKey = serviceAccountKey.PrivateKey
}

won't work, because 1. later I would need to access object props of, say, serviceAccount, but this variable scope is limited by

if

block 2. `export`'s seems to be not allowed in nested blocks in typescript
