Mobile SDKs Now Supports Archive Functions

We added archive APIs to our [Android](https://github.com/trycourier/courier-android/blob/master/Docs/Client.md#inbox-apis), [iOS](https://github.com/trycourier/courier-ios/blob/master/Docs/Client.md#inbox-apis), and [React Native](https://github.com/trycourier/courier-react-native#readme) SDKs, allowing you to build a swipe left to remove from the Courier Inbox. Enable your users to declutter their inboxes and keep only the notifications they want to save for later.
