Your CSS consists of your CSS Group at the top level. The only thing you can do here is to manage users on CSS Group level.
The actual CSS is the CSS Domain, located within the CSS Group. Here, you’ll find all relevant information, can invite users at the CSS Domain level, and add Merchant Center to your CSS. Navigate to the CSS Domain by clicking on the link in the “Domain” section at the bottom of the CSS Group.
Your CSS MCA is within your CSS Domain. All Merchant Centers added to your CSS are migrated to this specific MCA. You also need the ID of your CSS MCA for Merchant Center CSS-switch requests. Access your CSS MCA from your CSS Domain by clicking on “Merchants” in the left navigation bar.
