wsListen/wsAwait missing for SSE checks in Gatling 3.0

Hello everyone,

We moved from Gatling 2.3 to 3.0 and everything went good when we changed our scripts for classic HTTP endpoints testing. But this morning, we wanted to refactor our scripts for WebFlux (text/event-stream) endpoints using SSE testing. And we discovered that the check methods wsListen/wsAwait were missing in Gatling 3.0 !!!

We are trying to figure something out using checkIf method but we really need a continuous asynchronous way to check criteria among the data flow.

Does anyone figure how to do it without the wsListen/wsAwait methods with Gatling 3.0 ?

Thanks
