How do I implement mobile image crop in UE4?

I want to implement image crop in my mobile game with ue4 and It seems ue4 doesn’t offer any kind of function with that.

So in my opinion, only way to make this is to implement image crop in native (Android or Swift) and wrap it with UPL and add it to my UE4 project. Is there any other way? If not, how can I convert my own native image crop activity(in Android) to UPL?
