/**
 * Whether `tryExecute` surfaces a notification for this error.
 *
 * This is the single definition of that rule: `tryExecute` uses it to decide whether to notify, and callers
 * that add their own fallback messaging use it to avoid duplicating or contradicting the notification the
 * user has already been shown.
 * @param {unknown} error The error to inspect, typically the `error` of an `UmbApiResponse` or the `cause` of a wrapping error.
 * @returns {boolean} True when a notification is shown for this error, false when it is suppressed.
