groovyConsole: email option not working on cloud

[nutmix]

we added an osgi config file like this:

{
"allowedGroups":[
"groovyAdmin",
"admin"
],
"emailRecipients":[
"me@mydomain.com"
],
"auditDisplayAll":true,
"emailEnabled":true
}

And we can see this is "loaded" onto our cloud instance by scripts only being runnable by users in "groovyAdmin" group which we added.

however, no emails are received to the emailRecipients.

Is this feature broken for cloud?
