 Slack's [chat.postMessage](https://api.slack.com/methods/chat.postMessage) method accepts a JSON payload containing options — this JSON payload should be supplied as the argument in your GitHub Action. At a bare minimum, your payload must include a channel ID and the message. Here's what a basic message might look like:
 
 ```workflow
-action "Post message to Slack" {
-  uses = "pullreminders/slack-github-action@master"
-  secrets = [
-    "SLACK_BOT_TOKEN",
