Help for Aimeos

Hi, I have a fresh Aimeos Laravel Package installed, added an Admin user and a Site name "siteA". Now I want to create a separate Admin for "siteA". How can I do that so that "siteA" has a different Admin, who can manage all his products or shop.
I read the docs at https://aimeos.org/docs/User_Manual/Adm ... with_sites but still not getting the solution.
(Yes multi vendor shop I am talking about).

Have a look at the help of the "aimeos:account" command. You can specify the site code of the user.
