App-level webhooks: any of your app's store tokens works

For app-level webhook targets, filters and app subscriptions, any store access token your app holds works for every call. That includes updating or deleting an object you created with another store's token.

These objects belong to your app, not to a store, so they stay when a store uninstalls your app. Only that store's store-level subscriptions are deleted.
