How can I correctly read/use the parameters in partition zb_fct written by esp_zb_mfg_tool.py tool? (TZ-1235)

Question

According to the document mfg_tool:

1. Generate bin

python3 esp_zb_mfg_tool.py -i 966b9f3ef98ae6059708 -m 0BE961FEFFBD4D74 -c 0x8000 -mn XXXX -mc 0x1111

Created NVS binary: ===> /Workspace/esp-zigbee-sdk/tools/mfg_tool/bin/0BE961FEFFBD4D74.bin

Files generated in /Workspace/esp-zigbee-sdk/tools/mfg_tool/ ...

2. Flash memory

esptool.py -p  /dev/cu.usbmodem14214401 write_flash 0xf5000 bin/0BE961FEFFBD4D74.bin
esptool.py v4.8.dev5

3. Try to check if the zb_cft is correct

esptool.py -p /dev/cu.usbmodem14214401  read_flash 0xf5000 204 zb_fct.txt

diff bin/0BE961FEFFBD4D74.bin zb_fct.txt 
Binary files bin/0BE961FEFFBD4D74.bin and zb_fct.txt differ

It is pretty straightforward and make the all things done. However, I try to esp_zb_secur_ic_get after esp_zb_init:

...
 esp_zb_init(&zb_nwk_cfg);
 esp_zb_secur_ic_type_t ic_type = ESP_ZB_IC_TYPE_64;
 uint8_t *ic = esp_zb_secur_ic_get((uint8_t *)&ic_type);
...

The returned ic (install code) pointer is still NULL.

My questions are:

1. Is the zb_fct I flashed will be loaded by esp_zb_init?
2. What is the correct way to load the parameters I flashed? Install code, manufacturer name and code etc. ...?
3. I know I can manually set install code (manually) on the fly as well as manufacturer name and code by set attr, but how can I do with the pre flashed data?

Additional context.
