Report unhandled promise rejections

The Embrace SDK can be configured to automatically log an error with a stack trace when it detects a promise rejection that wasn't handled. This does add overhead to the use of Promises in your app so the feature is opt-in and can be turned on using the trackUnhandledRejections flag:

const { isStarted } = useEmbrace({
  ios: { appId: '__APP_ID__' },
  trackUnhandledRejections: true,
});

Note that this sets up a handler which supersedes the one setup by React Native for tracking unhandled promise rejections, in particular in dev with this enabled you will no longer see this popup:
