How to create website from whmcs ?

I have a problem when activating the service via whmcs.

the account creation process is successful, and can be used to log into the control panel.

but after logging into the control panel, the domain is not in the list,

Is there a special ACL for this? or is the module only capable of creating accounts?

then how do I get the domain to automatically appear on the list after activating the service?
