Lib-jitsi-meet sendCommandOnce does not output anything


starting from the lib-jitsi-meet example I’m trying to use room.sendCommandOnce(command,values) but I’m not getting any result from the action, nor output nor any return from the function. Is that normal ?
Has anyone got a working example of this command ?

Thanks in advance

you’ll need to add a listener for the command. check inside conference.js file. there you’ll find code examples on how to do it. search for this.commands.defaults.
