+ * An ErrorBoundary component that handles ElementCalls errors that can occur during a group call.
+ * It is based on the sentry ErrorBoundary component, that will log the error to sentry.
+ *
+ * The error fallback will show an error page with:
+ * - a description of the error
+ * - a button to go back the home screen
+ * - optional call-to-action buttons (ex: reconnect for connection lost)
+ * - A rageshake button for unknown errors
+ *
+ * For async errors the `useCallErrorBoundary` hook should be used to show the error page
+ * ```
