From what I understand, each RPC has a ChannelSet which is a set of channels that the RPC uses to connect and relay messages back and forth. I have looked at the API docs and we have access to the ChannelSet from the RPC object. However, the ChannelSet does not give us direct access to the channels in it. Instead, it only contains an array of Channel Ids. I want to get direct access to all the Channels in a ChannelSet for a particular RPC - can anyone guide me on how I could go about doing that? Is there a way to get access to a Channel given its id?
