global auth for all sites is not disabled after deleting user

when creating a new global auth user i.e "ee auth create global" it password protects all sites. deleting the new user does not deactivate the password prompt on all sites. on https://easyengine.io/commands/auth/delete/ it says use the command below but it does not work

Remove global auth on all sites (but not admin tools) with default username(easyengine)
$ ee auth delete example.com --site

Error: Parameter errors:
unknown --site parameter

I found a workaround by running ee global auth delete (this deletes all users and generates a new auth for ee-admin tools) after you will need to create a new auth for any site on the server i.e "ee auth create example.com" and then delete "ee auth delete example.com"

these steps remove the password prompt from all sites.
