agent.app.bsky.feed.getFeed language ?

[socialatm]

How do I get the preferredLanguage here?

const { data } = await agent.app.bsky.feed.getFeed(
  {
    feed: "at://did:plc:z72i7hdynmk6r22z27h6tvur/app.bsky.feed.generator/whats-hot",
    limit: 30,
  },
  {
    headers: {
      "Accept-Language": preferredLanguages,
    },
  },
);

I've checked agent, profile, preferences etc... and not finding the setting.
I'll assume it's operator error on my part. Thanks for any help.
