在特定网站上隐藏聊天框

Is your feature request related to a problem? Please describe.

I want to hide the chat box from appearing on specific websites. I want to hide it from google.com and duckduckgo.com. Currently, it always shows at the top of my searches and I can't find any way to remove it. I'm not sure if this is possible to do, but I haven't been able to find a way to do so. There is an option, however, to disable it for some specific sites (e.g., YouTube, Quora, Reddit, etc.) under Modules > Sites, but Google nor DuckDuckGo are options among them.
