can someone tell me how to change size of the chess board when i'm on focus mode?

When I play, my board becomes small and I can't make it bigger. How can I fix that?

(I need to change focus mode off to make the board bigger.)

Hae you tried the following?

https://support.chess.com/en/articles/8609533-how-do-i-change-my-board-size

hover over exactly where you would change the board without focus mode

and if you don't know how to change the board, @Martin_Stahl gave you an article which shows how too.

If you have something with a keyboard, just press “z”

I mean, when the focus mode is on, the article says that the board will become bigger, but my board in focus mode is smaller than the board in normal mode. Am I doing something wrong?
