Overview
The Send Message activity uses the Slack chat.postMessage API (among others) to send a message (Text) to a specific channel or direct/group message (Conversation).
After sending the reply, the activity returns its properties in Message
object (Message) that you can use as input property variables in subsequent activities (e.g. Get Replies, Message.Text
in Write Line, etc.).

- Add the Slack Scope activity to your project.
- Add the Reply activity inside the Slack Scope activity.
