Usage info​

Based on certain conditions, you can reply to a message in-thread.

Example workflow step​

const replyInThreadStep = ExampleWorkflow.addStep(
  Schema.slack.functions.ReplyInThread,
  {
    message_context: sendMessageStep.outputs.message_context,
    reply_broadcast: false,
    message: "Thank you for submitting a message to #sos, Gilligan.",
  },

To reply in-thread with buttons, they must be wrapped in a block (example: section block). Then, use the workflow_button element.
