Recover publishers after reconnect

We have 1 connection to Janus API for multiple clients, using different handles. And have multiple connections to our wrapper around janus.
My question is: when connection to our wrapper lost, but there is still connection from wrapper to janus as well as publisher’s and subscriber’s handles existing, how to recover videoconference state?

Answer on all your questions is very good described in janus doc

You ask janus community how to recover connection to YOUR wrapper?..
