/**
 * Generic alert type with required fields for display. The `element` field will be rendered in
 * the Cost Insights "Action Items" section. This should use data fetched in the CostInsightsApi
 * implementation to render an InfoCard or other visualization.
 *
 * The alert type exposes hooks which can be used to enable and access various events,
 * such as when a user dismisses or snoozes an alert. Default forms and buttons
 * will be rendered if a hook is defined.
 *
 * Each default form can be overridden with a custom component. It must be implemented using
 * React.forwardRef. See https://reactjs.org/docs/forwarding-refs
 *
 * Errors thrown within hooks will generate a snackbar error notification.
