channels are not working with cloudflare workers

[xydv]

so i setup'd a basic application using workers,

channel

import { createChannel } from "better-sse";

const channel = createChannel();

export { channel as orderChannel };

/register to channel

import { createResponse } from "better-sse";
import { Hono } from "hono";
import { orderChannel } from "../channels/orderChannel";

const app = new Hono();

app.get("/register", (c) =>
  createResponse(c.req.raw, (session) => {
    orderChannel.register(session);
  }),
);

export default app;

/broadcast to channel

import { Hono } from "hono";
import { orderChannel } from "../channels/orderChannel";

const app = new Hono<{ Bindings: Env }>();

app.post(
  "/broadcast",
  async (c) => {
    orderChannel.broadcast("hi");
    return c.json([]);
  },
);

export default app;

upon subscribing to /register and sending events doesn't work, is it because of the serverless nature?
