Delete chat message client side

[TheidenHD]

I am currently Porting a mod from 1.19 to 1.20.1, one of the Items writes some information into the chat when used. To prevent spamming older messages are deleted. 

public boolean receive(Supplier<NetworkEvent.Context> context) {
		context.get().enqueueWork(() -> {
			ChatComponent chatGui = Minecraft.getInstance().gui.getChat();
			chatGui.deleteMessage(signature);
			chatGui.addMessage(message, signature, GuiMessageTag.system());
		});
		return true;
	}

In 1.20.1 it doesn't work anymore. The Message gets replaced after 60 Seconds with a message saying: "This chat message has been deleted by the server."
