The proxy is working... But how?

[AcedWorld]

Hi when I do this the proxy works
But I don't understand how it works sorry as usually with other browser automations I have to supply the username and password
I do have my IP whitelisted with oxylabs so I think that's what makes it work?
But what if I didn't have my IP whitelisted how could I specify the username and password? Thank you! 😁

options = Options()
options.add_argument('--proxy-server=http://ip:port')
async def main():
async with Chrome(options=options) as browser:
await browser.start()
page = await browser.get_page()

    # Works with captcha-protected sites
    await page.go_to('https://whatismyipaddress.com/')

Try options.add_argument('--proxy-server= "login:password@ip:port" ')
