Question aliasdomain.com to www.aliasdomain.com

[dj ramc]

Server operating system version

AlmaLinux 8.10

Plesk version and microupdate number

18.0.63 Update #4

I've been trying to get this working for a while now, but without success.
I'm trying to forward aliasdomain.com to www.aliasdomain.com.
Forwarding of domain.com to www.domain.com is already working.
Any suggestions are welcome.
Thanks in advance.

I've done this with adding nginx code below in
Additional nginx directives

if ($host !~* ^www\.) {
return 301 $scheme://www.$host$request_uri;
}
