Wont work on GraphQL Yoga

Description

• Seems like this wont work on GraphQL Yoga, but upon setting it up there are no errors
• Already tried putting the Socket.io config after server.start but no luck

const express = require('express');
const { GraphQLServer, PubSub } = require('graphql-yoga');
...
const graphQLServer = new GraphQLServer({
  typeDefs: TYPE_DEFS,
  resolvers,
  middlewares: [yupMiddleware()],
  context: request => {
    return {
      ...request,
      prisma,
      pubsub,
    }
  },
})
server.express.use('/uploads', express.static('uploads'))
...
const io = socketio(graphQLServer)
io.on('connection', async (socket) => {
  console.log('a user connected');
});

Start with the provided GraphQL Yoga and Express setup, then reproduce the Socket.IO initialization shown in the issue and inspect the server integration entry points. Done means establishing a working client connection in this setup or documenting the confirmed compatibility limitation and required configuration.
