Update: Nevermind, digging deeper into the python library it doesn't look like it's possible directly; only by harvesting contacts and matching from there.

This use case is when writing bots, but when you receive a message in a channel there doesn't seem to be a way to send a private/direct message reply to the user. For example, you receive:

meshcore/message/channel/1: {"type": "EventType.CHANNEL_MSG_RECV", "payload": {"type": "CHAN", "channel_idx": 1, "path_len": 0, "txt_type": 0, "sender_timestamp": 1777763887, "text": "User-1: test"}, "attributes": {"channel_idx": 1, "txt_type": 0}}

And you then try to send a message to destination 'User-1' it fails with: Invalid public key hex string: User-1
