Django not loading static files from React build folder

I am not able to load CSS and JS files in React frontend. I am running Django and react on same server.

Django setting file

STATICFILES_DIRS = [
    os.path.join(BASE_DIR,'static'),
    **os.path.join(BASE_DIR, '../frontend/build/static')**
]

After I run npm run build and check the django its not loading the static files.
