Bin font usage with spesific flash memory address

I use NXP Imx RT1170 series mcu and I want to use font as a bin format. How could that possible ?

I see there is a source file as lv_binfont_loader.c but this file is not in the latest tag, it exists in master branch. Why the tag does not include this file ? Is it still in progress ?

I have downloaded offline lvgl font converter and have got bin font file with script. After that I have written this bin file into flash’s spesific address and used below functions but I could not see anything in screen. I am open any advice.

lv_font_t my_font;
static lv_style_t font_style;
lv_style_set_text_font(&font_style, &my_font);

lv_obj_t *label_zh = lv_label_create(ui->screen);
lv_obj_align(label_zh, LV_ALIGN_BOTTOM_MID, 0, 0);
lv_obj_add_style(label_zh, &font_style, 0);
lv_label_set_text(label_zh, "china font");
