Social Login doesn't return token even after enabling the `bearer()` plugin

export const AuthClient = createAuthClient({
  fetchOptions: {
    onSuccess: (ctx) => {
      const token = ctx.response.headers.get("set-auth-token");

      if (token) {
        console.log(token);
        window.postMessage({ action: "READLATER_AUTH", token });
      }
    },
  },
  plugins: [polarClient(), lastLoginMethodClient()],
});
