Is there way emit everyone except sender/"person who made request" inside express route

Hi,
I was wondering is there way emitting everyone except sender inside express route?

router.post('/test', (req, res) => { const io = req.app.get('io') // Will send everyone including to the person who made request io.to("room").emit('txt', data) // Will also send everyone including to the person who made request io.socket.to("room").emit('txt', data) ... })

It should be doable with express-session:

io.on("connection", (socket) => {
  // join the room identified by the session ID
  socket.join(socket.request.sessionID);
});

router.post("/test", (req, res) => {
  // send to everyone except those in the given room
  io.except(req.sessionID).emit(/* ... */);
});

For the setup, please see https://socket.io/docs/v4/faq/#usage-with-express-session (until we have a proper example with express-session)
