WebSocket Audio Testing On Gatling

Hello Floks,

I am new user for Gatling. I am trying to do a load test with web sockets to do some post call by sending some audios as content in the header . I am not able to get how to do that .
I didn’t get enough information from the official documentation as well .
I would really appreciate it if you could provide some examples on how we can do it ?

Thanks
