SSL certificates / email accounts...

Hi,

I use Alma linux 9.5 and CWP… I log in to the CWP with root and create a user with domain1.com...
1. I need to add domain domain2.com to the same user, where does this happen via root or through the user panel?
2. Where are the SSL certificates for the two domains created - via root or in the user panel?
2. Where are the email accounts for the two domains created - via root or in the user panel?
