How do I disable the "ask to unmute" notification when I speak unmuted?

Yeah so when I speak and I am muted, the zoom would show an annoying notification in the middle of the screen, "Your mic is muted..... unmute or press space bar blablabla". I don't need that because I am not blind. How do I disable it? I don't see an option in Zoom for that.
