[MM3-users] Where do I find the check_hk_archive script

In https://docs.mailman3.org/en/latest/migration.html I'm adviced to run the check_hk_archive script found in hyperkitty/contrib. When trying git clone https://gitlab.com/mailman/hyperkityI get:

Username for 'https://gitlab.com':

Is it possible to get the script without an account on gitlab?

Thanks, Lars
