Sending ws messages in parallel to the main scenario

Hi All,

I apologize in advance if my questions are too stupid,
I’m newbie in Gatling

I have a scenario that interacts with the site via WebSockets. And I need to send a certain message once in interval time, into an already open connection. How can this be done? Two scenarios, but how then to send the message to the right connection without opening a new one?

Thanks
