How can I remove the chat logs, but preserve the text GUI?

You want to remove the Chat Box in the top left corner but keep the chat bubble? It's annoying that Roblox removed that feature but what you want to do is:

1. Press play in Studio
2. Open "Chat" in Explorer
3. Only copy "ClientChatModules"
4. Stop playing in studio and paste "ClientChatModules" into "Chat"
5. Delete everything except "ChatSettings"
6. Open the script and go to lines 27 & 28 where it says

--- Replace with true/false to force the chat type. Otherwise this will default to the setting on the website.
module.BubbleChatEnabled = PlayersService.BubbleChat
module.ClassicChatEnabled = PlayersService.ClassicChat

Then delete "PlayerService.BubbleChat" and "PlayerService.ClassicChat" and put true for bubble chat and false for ClassicChat

I hope this is what you meant. If this is still complicated here is the ChatSettings script

--  // FileName: ChatSettings.lua
--  // Written by: Xsitsu
--  // Description: Settings module for configuring different aspects of the chat window.
