This isn't a request in the sense of the library asking the library user
"may I?"; it's an object that represents an unfinished request for a channel.
You ask the channel dispatcher to make you a channel; later (because it
might take a while), you get a response like "OK, here is your channel" or
"sorry, I couldn't do that". One of the possible failure reasons is that you
decided you didn't want the channel after all, and called Cancel; others are
things like a network error.
Proceed is only there for D-Bus API reasons and shouldn't be visible in the
My mail "Semantics of the ChannelDispatcher" explains further.
