Getting client_responder_id from peer_responder_id

Hi everyone,
I was wondering if there is any way to get the client_responder_id when I only got the peer_responder_id.

The other way around, having the client_responder_id, I can send a gRPC (/consensus_client.ConsensusClientAPI/GetNodeConfig) ; that works like a charm, but I think, I need the »other direction«.

Thank you in advance for helping me out!

Whish you all a great day!
