close

Closes the ServerSSESession, terminating the connection with the client. Once this method is called, the SSE session is closed and no further events can be sent. You don't need to call this method as it is called automatically when all the send operations are completed.

It's important to note that closing the session using this method does not send a termination event to the client. If you wish to send a specific event to signify the end of the SSE stream before closing the session, you can use the send function for it.
