Web sockets

Can Xano generates web sockets currently?

Would you guys consider installing web socket library like socket.io for lamba /nodejs?

I am trying to have real-time comms to my front end react native app - I was considering push notification as an alternative but I am afraid that user would be able to block push notification and then all the functionalities would fail. Do you guys have any other ideas and suggestion? Basically one user sends a request to the other user that has to be confirmed immediately. Do you see any other ways of achieving this with Xano?
