UserController

All Implemented Interfaces:
```
public interface UserController

                    
```
A UserController manages registration of user and respective FCM and MHS push tokens for Sinch Managed Push functionality. Use UserController as a lightweight tool that allows to register user for incoming calls via Managed Push functionality without a necessity to start SinchClient. When PushTokenRegistrationCallback.onPushTokenRegistered is called, you can be sure, that incoming calls will be received via FCM or HMS push notifications and you are free to close/terminate application if desired.
Note: The callback will be invoked on the same thread as the UserController is instantiated on.
