[maxceem]

Form @vikasrohit

we might need to get rid of connect specific consumers https://github.com/topcoder-platform/tc-notifications/tree/dev/connect and instead use the generic consumer as it's done for other notifications https://github.com/topcoder-platform/tc-notifications/blob/dev/consumer.js

@sachin-maheshwari do you think we can now move Connect specific consumer to the generic consumer? It would be great if you can share the details about procedure to do so?
