How create room with different MaxClients in client-side?

Hi, everyone!
How create room with different MaxClients in client-side?

Thank for all!

i think you need send options max client to server
Example:
1.client
client.join("chat", {max_client:max_client});
2.server
onInit(options) {

var max_client = options.max_client;
this.maxClients= max_client;

}
