How do I set selenium-side-runner to read cookies?

Question

I record a test in Selenium IDE which takes login details from a cookie. The test runs fine in Selenium IDE but using the command line SIDE Runner it fails to fill in the login details & the test fails. The only clue I've found is Selenium Webdriver needs something like this: chrome_options.add_argument(f"--remote-debugging-port=9222")

selenium-side-runner -h options are probably relevant ?

If I type the login details during record the actions are not recorded. I could probably fix this but cookie reading in selenium-side-runner should be possible ?
