Using Slack's built-in incoming webhook capabilities to send a message: https://slack.dev/python-slack-sdk/webhook/index.html

Running

In Slack:

2. Install app to workspace & choose the target slack channel. From app page, select Settings -> Install App

3. Copy the webhook URL from the bottom of the page.

In cnvrg:

4. Define a new secret in your cnvrg project: Go to Settings -> Secrets -> Add. Set the secret's name to be SLACK_WEBHOOK_URL, and the value to be the URL.

5. Choose the Slack AI Library component, and pass the text you'd wish to send, to the message argument.
