How to use subscription with bullmq?

How can I process the messages in the queue with bullmq in the worker and publish them on the subscription side? I can't solve it in any way. My trpc server is published on my own nodejs server. What I want to do is as follows, but we can't use yield in eventlistener. What is the right way?

import { Queue, Worker } from "bullmq";

const sendMessage = publicProcedure
  .mutation(async ({ ctx }) => {
    const myQueue = new Queue(`match-message`, { connection:ctx.redis });
    await myQueue.add('test', 'test message');
    return true;
  });


const onMessage = publicProcedure.subscription(async function* ({
  signal,
  input,
  ctx,
}) {

  const worker=new Worker(`match-message`, async (job) => {
    return job.returnvalue as Message
  },{
    connection:ctx.redis
  })
  worker.on('completed', (job) => {
    // yield message
  })
  if(signal?.aborted){
    worker.close()
  }

 
});

  signal,
  input,
  ctx,

  const worker=new Worker(`match-message`, async (job) => {
    return job.returnvalue as Message
  },{
    connection:ctx.redis
  })
  worker.on('completed', (job) => {
    // yield message
  })
  if(signal?.aborted){
    worker.close()
  }

 
});
