User Problem

Currently whenever a request participant is added to a thread , we notify the added participant in the requester thread that exists in a channel.

But There are use-cases where the issue is raised outside of the slack channel. In this case , the request thread exists in a DM with the bot.
Any added participants to the jira ticket are not notified on slack in this scenario.

Additionally,  if the request participant is not part of the request channel, they do not receive any notifications either. 

Suggested Solutions

When the request thread exists in DM with the bot and any participants are added to the issue, send DM to the participant with the issue preview.
Also, notify the participant when any comment is added to the requester thread.
