Apologies but I’m not sure I understand which “3 dots” you’re referring to. Would you mind clarifying?
Are you referring to these three dots below?
@tatortman, thanks for clarifying!
The three dots you’re seeing there are not a Brave theme. Rather, they are the
Maximize buttons that macOS devices use.
To solve this: buy a macOS enabled device! Unfortunately its a rather expensive workaround
Let me know if anything is still unclear!
