[1.16] Disable IME when open chat screen

[Zemelua]

I'm trying to make Japanese input easier now. It may not be related to Minecraft, but I have two questions.

1. How can I force IME to be enabled when the chat screen is opened and disabled when it is closed?

2. The character string being input (before conversion) in IME will not be displayed on the chat screen (it will be displayed after confirmation). For this reason, I want to get the string I'm typing and add it to ChatScreen.inputField. How can I get it?

public static void onChatOpen(GuiOpenEvent event) {
	if (event.getGui() instanceof ChatScreen) {
		// enable IME, how?

		// InputContext.getInstance().setCompositionEnabled(true); <- always throw exception...
	}
}

I also searched but couldn't find ... isn't there other way to do this?
