Can I filter the drift notifications in OpsCompass?

Yes, you can filter by concern, cloud provider, cloud accounts, user, resource types, alert types, and date.

Use the filter button to select the items you want to filter by, and click the "Apply" button. You can double click any item to quickly focus in on that specific item, specify a resource type, and/or select a date range.

How do I enable additional concerns?
