How to remove chatbox panel?

Could someone please help me with a piece of code that can remove the chat box panel in-game for a gamemode? Basically I want the chat to work and come up but I just don’t want the bold grey panel that surrounds it. Thanks in advance.

The only way would be to override the chatbox and create your own.
Something like this would work if you don’t know how to do it yourself.
