font-size of sp-textarea

I am rebuilding CEP to UXP and am having trouble changing the font-size of sp-textarea.
Currently, the text is too small and difficult to read.
The documentation says “Text edit fields do not support font size.” Is there any way to change the font-size?
Also, is there any possibility to change the font-size in the future?
I would like to change the font-family if possible, but this also does not seem to be supported at this time.
