Spring Boot - Angular websocket libraries choice and communication

I have found that there are two ways to connect a Spring Boot backend with an Angular frontend,

1. Spring: regular spring-websocket broker, with Stomp. Angular StompJS and SockJS
2. Spring: netty-socketio which is a port of socketIO. Angular Socket.IO

For 1), The SockJS and StompJS are outdated and not maintained. Spring is up to date with full capabilities

For 2), Socket.IO is the most modern to use with Angular, Spring: the netty-socketio is just a port for java, it does not have all the possibilities of the regular reactor web library

All guides mention spring the regular way with broker and stomp, like Baeldung and all Angular guides are about SocketIO.

However, I have not found a way for them to mix ? Can it be done and I am missing something? What is the best and most modern way to make such a web app now?
