Sending custom email from Builtin Scripts Post Function missing

JT4

I am trying to send a custom email to Project Leads based on the Reporter field. I've got Script Runner v2.1.4 and JIRA v6.0.2

I have followed the instructions here:

https://jamieechlin.atlassian.net/wiki/display/GRV/Built-In+Scripts?src=contextnavchildmode#Built-InScripts-SendCustomEmail

and was able to run the preview using the following:

condition: issue.reporterId == "sd.auto.submit"

email template: Dear Project Lead ........

email subject: A new Auto-Submit issue

email format: plain text

to issue fields: projectLead

When I preview the email with my test configurations, the conditions validate to true or false (based on the preview issue key).

I then went to the workflow to add the Post Function, but I do not have a 'Send Custom Email' post function. Where/How do I find the Post Function?

Looking at the modules for the plugin, all modules are enabled.

In post-function , you can find "Script Post-Function" option. This one is the correcti option.
