    * sending messages into it. The surrounding code will have to ensure the correct
    * membership state itself in this case. Default: false.
    *
    * @param opts.enablePresence True to send presence, false to no-op.
    *
    * @param opts.caching.ttl How long requests can stay in the cache, in milliseconds.
