how to create rooms with my own

I found that all room id is generated automatically, such as "id":"pc_SOfe8u", and so as session id such as "sessionId":"xYrMyDFdH", and also websocket url:connection":{"url":"ws://localhost:2567/1O39f7sxi/pc_SOfe8u?sessionId=xYrMyDFdH" .

it seems that i can't control or manage this information on my own. If I want to issue my own customized, or url, how to do?

@sunq0001 I saw the reply in github, thanks a lot. we can close it.
