How to emit an event from a separate process?

Question

Node.js

There is a web application on Node / Express / Socket.io
When performing a difficult operation, I connect the Bull task queue, which creates a separate process for the task. But now it’s not clear how I can send an event to the client who sent the initial request from this task-process?

socket.io.emit(`imageprocessing:${job.id}`, finaleResult)

This does not work from a separate process. Apparently because the process does not know which client to send? Do I need to re-raise the websocket server separately in this process (for example, I had to re-raise the connection to Monge there) How to fix it?
