Currently I have requester A, B and C and have a replier
1. Is there a way that I can query the replier object to get the participant name of the requesters A,B and C that is connected to it. Assuming the requesters have not send any request yet.
2. is there a way to install a listener to a replier so that whenever there is a new connection/disconnection from the a requester, the replier will be informed.
