How to customize the font in the insert_textbox function

[TCHSDUFH]

When using the insert_textbox function, I want to use some Chinese fonts, such as SimSum.ttf. I checked the source code of the function and found that it doesn't support this font. It's also not possible to directly assign a local font file path. How should I proceed to make the inserted text use the SimSum.ttf font? tks

page.insert_textbox(rect,
                            nowPage,
                            fontsize=int(pageFontSet.fontSize),
                            fontname='D:\\SimSum.ttf',    
                            color=pageFontSet.fontColor,    
                            align=TEXT_ALIGN_CENTER,  
                            overlay=True)  #
