In Nodejs or noflo I can register the prticipant under the name. But in python How to register the participant

msgflo-nodejs --name repeater ./node_modules/msgflo-nodejs/examples/Repeat.coffee

Here I registered the participant under the "repeater" name. So I can send message to repeater.IN in mqtt. But how to do that for msgflo-python?

I'm following the example here -> https://github.com/msgflo/msgflo-python

Kindly help me on this. Thanks in advance :)
