AllowedInputMethods

Setting the policy lets users choose one of the input methods for Google ChromeOS sessions that you specify. If you leave it unset or set to an empty list, users can select all supported input methods. Starting with version M106 allowed input methods are automatically enabled in kiosk session. Note: If the current input method is unsupported, it switches to the hardware keyboard layout (if allowed) or the first valid entry in this list. Invalid or unsupported methods are ignored.
