FE: Dismissed alerts can be hidden

Why are we doing this work

• when a user has remedied an alert, they want to dismiss it so that they know no more actions are required
• Once an alert is dismissed, it is less relevant than other alerts
• All a user to hide dismissed alerts

Design

Non-functional requirements

• Documentation: I am waiting until the end to update the documentation as this feature is behind a feature flag
• Feature flag: This feature is behind the threat_monitoring_alerts feature flag
• Testing

Implementation plan

• frontend hide dismissed alerts
  • maybe through a graphql filter
