What is Wrong with my Trigger ?

There’s your problem.
Zammad will, at no point, send any Trigger based mails out to customers, if you don’t have a mail address configured to your group.

Technically, if you don’t want to receive mails for whatever reason, you could use outbound only channels (because you need a channel to assign to the group…):

If you ignore the above, this is the correct trigger configuration that will do what you want, based on an agent writing a public note.
