Send alert when data is created in app/database

This template shows how you can take any event from any service, transform its data and send an alert to your desired app. Specifically, this example monitors a Linear project for new bug submissions. Then it only sends a Slack notification to a channel if a new bug is urgent. You can swap the Linear trigger for another Task Management app such as Jira or Asana; or an entirely different usecase. Setup instructions are located inside the workflow template.

Help me set up the n8n workflow "Send alert when data is created in app/database" (https://n8n.io/workflows/1932). It uses: Slack, Code. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
