Extension Chat Message returns 401 authentication failed

Hey @BarryCarlyon I tried this

const sec = "mysecret_key";
const secret = Buffer.from(sec, "base64");
const bearerPrefix = "Bearer ";

const sigChatPayload = {
  exp: Math.floor(new Date().getTime() / 1000) + 4,
  channel_id: "152826156",
  role: "external",
};

const sigChat = jsonwebtoken.sign(sigChatPayload, secret);
const client_id = "y7aqa290cuap0tqrvs44t3wr9qu20f";
got({
  url: "https://api.twitch.tv/helix/extensions/chat",
  method: "POST",
  headers: {
    "Client-ID": client_id,
    Authorization: "Bearer " + sigChat,
  },
  json: {
    broadcaster_id: 152826156,
    text: "This is a Test Message Kappa",
    extension_id: client_id,
    extension_version: "0.0.1",
  },
  responseType: "json",
})
  .then((resp) => {
    // console log out the useful information
    // keeping track of rate limits is important
    // you can only set the config 12 times a minute per segment
    console.error(
      "Send Chat OK",
      resp.statusCode,
      resp.headers["ratelimit-remaining"],
      "/",
      resp.headers["ratelimit-limit"]
    );

    // we don't care too much about the statusCode here
    // but you should test it for a 204
  })
  .catch((err) => {
    if (err.response) {
      console.error("Errored", err.response.statusCode, err.response.body);
      return;
    }
    console.error(err);
  });

But still getting

I am live on the broadcaster channel and have the extension installed there as well
