Add a "Submit Conversation" button to the Slack integration

We would love to have an option for conversations to be created by our reps on a customer’s behalf via a button in the Slack/Intercom integration. Currently, there is a ticket option for this, but our team starts almost all of our client interactions in the conversation format, and we try to only use tickets for longer running issues, complex questions, or bugs. Adding a button for this would also allow us to remove the custom Slack workflow we created that allows users to create conversations via the API, which is a more complex and non-native version of what we would like to do.
