I confirm.
I used to see it under “Appearance” -> Email Templates. But not now.
It seems to me that it is correct there (as a submenu) so that the WordPress side menu does not become so long.
Let’s agree that it is not a function that is used constantly.
I have the same problem. Also, the option to edit the “email template” doesn’t appear.
