New Witcher 4 Character Leaked?

We know that Geralt is set to have a supporting role in Witcher 4, and it appears we might have the first new character to look forward too. A recent CV of an actor in the game codenamed Polaris lists Branko as the role in the game. CD Projekt has said the goal of Witcher 4 is to win back fans still burned over the Cyberpunk 2077 release.
