1. Define the function using `inngest.createFunction`.
2. Break down the workflow into individual steps.
3. Use `step.run` to execute code, ensuring all non-deterministic logic is within the step.
4. Use `step.sleep` to pause execution for a specified duration.
5. Use `step.waitForEvent` to wait for specific events, handling potential timeouts.
6. Use `step.sendEvent` to trigger other functions.
7. Use `step.invoke` to call other functions and handle their results.
8. Implement error handling and retry logic within each step.
