OBS Studio 31.0.1 remove UI directory, how can I get replaced API?

[clareli385]

OBS Studio 30 can support GetProfilePath function in UI/obs-app.hpp to get basic.ini path for basic profile settings. But In nvew version OBS Studio 31.0.1, just remove UI directory. I try to call GetUserConfig() or obs_frontend_get_current_profile() or obs_frontend_get_current_profile_path() in frontend\OBSApp.hpp, and I still cannot get basic.ini path for basic profile settings. How can I get the API function to access basic.ini?
