How to change font type, font size, and row(or column) name in correlogram using cor_plot?

[Chanphit]

Dear Alboukadel Kassambara and others

I am creating a correlogram using rstatix and cor_plot within r_statix package. The variable I used to created correlegram was 10 in number. My correlogram showed the very large font on the circles inside correlogram, which made uneasily to visualize. Additionally, I would like to change the font type to "Times New Roman" and change label of variables that I used. Therefore, I would like to ask that How to change font type, font size, and row(or column) name in correlogram using cor_plot? Furthermore, how can I export the plot or correlogram in a tiff format at 300 dpi?

Thank you
