rotating proxies with scrapy with authentication

just a noob question but I can't seem to find the answer googling. how can i use this package https://pypi.org/project/scrapy-rotating-proxies/ if the proxy requires a user/password? do I just put it in the rotating list like that?

ROTATING_PROXY_LIST = [
    'https://username:password@proxy:port',
    'https://username:password@proxy:port',
    # ...
]

thanks
