import { trackNetworkStatus } from '@withease/web-api';

persist({
  store: $store,
  pickup: trackNetworkStatus
})

@@trigger protocol requires calling setup event, but for persist pickup is actually an analogue of setup. So, there is a loop, to add trigger to pickup we need to call pickup, which is trigger...

Maybe introduce new options setup and teardown?
