How to access logs of emails in Service Management

[Daniel Witkowski]

In Administration > Applications > Jira Service Management > Email requests, there is a list of Email addresses, each one with "View log" action. Is there a way to access these logs with sciptrunner through groovy? I searched through whole JSM documentation and couldn't find any class representing this information. I would rather not use SQL.
I wanted to also use REST API, but couldn't find anything either.
