Sharing or keyboard for iOS

For iOS, I would like the display of the sharing function and keyboard to correspond to the language of each region.
The region of the followings is Japan.

Keyboard at Google App

Keyboard at AppInventor

Sharing at Photo App

Sharing at AppInventor

Since the App Inventor companion app is only provided in English, I believe the standard controls provided by iOS default to English as well. Until we add localizations to the companion app I don't think the app will do as you're requesting.

Thank you for your reply.
I look forward to trying it by the .IPA file in the near future.
