Question : I want to send a message in my slack channel and get that text back from the bot present in the channel using github actions.

Tried: I have used the slack send github action where I have a github action workflow with the following code.

name: CI

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Post to a Slack channel
      id: slack
      uses: slackapi/slack-github-action@v1.18.0
      with:
        channel-id: 'C032NCAKJPR'
        slack-message: "Does it Work"
      env:
        SLACK_BOT_TOKEN: ${{ secrets.SLACK_BOT_TOKEN }}

With this whatever I enter in the slack-message will be sent in the channel by the bot. I am not sure how to proceed with getting the data from the channel and then passing that into this workflow so the bot sends the same text back.
