For Japanese  (Settings for Japanese Language Environment) does not work on iPhone Mirroring

Hi, It seems the command to switch back and forth between Japanese Kana and English does not work inside the iPhone Mirroring app on Mac OS 15.2.
The rule I used is: 
コマンドキーを単体で押したときに、英数・かなキーを送信する。（左コマンドキーは英数、右コマンドキーはかな） (rev 3)
