You did the the extension secret and not the extension client secret

For ease of testing lets also change

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

to

const sigChatPayload = {
  exp: Math.floor(new Date().getTime() / 1000) + 4,
  user_id: "The ID of the Twitch Account that owns the extension",
  role: "external",
};

and the broadcaster_id in the payload is not correct

  json: {
    broadcaster_id: 152826156,
    text: "This is a Test Message Kappa",
    extension_id: client_id,
    extension_version: "0.0.1",
  },

should be a string

  json: {
    broadcaster_id: "152826156",
    text: "This is a Test Message Kappa",
    extension_id: client_id,
    extension_version: "0.0.1",
  },

Also check the version numbers match. That 0.0.1 is active on the destination channel
