I haven't seen a conclusive answer. My search results suggest that she may be 22, but it is mostly based on the fact that she has some voice acting credits from 2003. Someone on Reddit mentioned that they read an article saying "(...) she moved to LA w her family when she was 6, and then took up acting classes “a while later”" and this suggest that voice acting would probably be after this. So she would be from 1997 at least and that would make her 25 (or more). The show had its premiere on January 2021.

Regardless it is remarkable or even more remarkable.

I looked her up, because my daughter was asking about her.
