How to access ESP-IDF bt.h include file

I am trying to set a ESP-IDF BLE gatt host project but am getting a missing include file error for bt.h and other bt files in my src/misc/ble_service.cpp. Any idea how to enable the BLE functionality? I tried playing with menuconfig but didn’t manage to make bt.h appearing.

#include "bt.h"

My project and sdkconfig are here:

These screenshots of the menuconfig state I saved.
