How to return connection session ID in Spring + STOMP?

Question

Java

Hello, I need to get the SessionId when a socket connection occurs.

What SessionId are we talking about, what identifies the socket connection.
An example in which you can get this very SessionId

@MessageMapping("/find")
public void find(SimpMessageHeaderAccessor sha, User user) {
    String sessionId = sha.getSessionId();
    LOG.debug("New session id - {}, {}", sessionId, user);
    // New session id - rs5ahsly, {user: Name, ...}
    Repository.add(sessionId, user);
}

Knowing the SessionId, you can send a message to a specific subscriber.

The question is, I need to return the SessionId when a connection to the server is established via the STOMP protocol. This is the response I want to receive from the server:

CONNECTED↵version:1.1↵heart-beat:0,0↵sessionId:rs5ahsly↵↵

For example, I can generate a unique user ID key with the code below, but this will return randomUUID

public class CustomHandshakeHandler extends DefaultHandshakeHandler {    
    @Override
    protected Principal determineUser(ServerHttpRequest request,
                                      WebSocketHandler wsHandler,
                                      Map<String, Object> attributes) {
        return new StompPrincipal(UUID.randomUUID().toString());
    }
}

How can I do something like this but return the socket's SessionId?
In my opinion, there is no access to SessionId from DefaultHandshakeHandler
