LGTM, but we can probably simplify it more later.
In staff-utils.js we have a way to show alert on every platform (getConfig().showAlert(title, message)), even though it's part of lib. Each platform implements its own way of showing the alert: on web it's window.alert(...), on mobile it's Alert.alert. Maybe we can do something similar for those alerts? Showing an alert seems like a common functionality, so maybe we can simplify it in other places too.

I think it is a good idea to simplify this, but I'm not sure if in this direction. The pattern that we can see here is quite unique - usually, we handle errors on a different layer than this, which is evident from the fact that other protocol functions don't need to receive an alert handler. So in this case I think that we should replicate the approach from other places and move the error handling to the component level.

Regarding adding a utility that shows this kind of alert, I agree that this will simplify some places now, but these places probably shouldn't use this pattern in the first place. So after making our UI more consistent, I would expect that there won't be any need to have this utility.
