+By default, `getSecret()` fetches and returns a personal secret. If not found, it returns a shared secret, or tries to retrieve the value from `process.env`. If a secret is fetched, `getSecret()` caches it to reduce excessive calls and re-fetches periodically based on the `cacheTTL` option (default is `300` seconds) when initializing the client — for more information, see the caching section.
