**Tell us about your request**
To show scheduled task that was triggered by EventBridge Rule and EventBridge Scheduler. We are using AWS CoPilot CLI to handle our ECS deployment and specifically using `type: Scheduled Job` for our copilot deployment.

**Which service(s) is this request for?**
ECS, Scheduled Task

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
I've tried to deploy scheduled job using AWS CoPilot CLI and expecting for the deployed job to show up as `Scheduled Tasks` in AWS ECS console but it is not. When I check in EventBridge Rule, it is there.
When the schedule/cron matched, it only appears as task in ECS console only, meaning if the schedule/cron is not matched, there is nothing to see in AWS console.

**Are you currently working around this issue?**
Nope.

**Additional context**
NA

Reference from AWS Copilot issue:
https://github.com/aws/copilot-cli/issues/3077#issuecomment-1710487585

Start with the ECS console's Scheduled Tasks view and compare it with the EventBridge Rule and EventBridge Scheduler resources described in the request. Check how an AWS Copilot Scheduled Job appears before and after its cron fires. Done means the console represents the scheduled task configuration even when no task has run.
