"status changed to" in scriptrunner

[Deleted user]

Hi all, I'm trying to write a filter that returns all Done issues that were put In Progress less that 30 days before they were changed to Done. I know in JQL we can do something like

status changed to "IN PROGRESS" during ("start date", "end date") 

and using scriptrunner in JQL I can do something like

issueFunction in dateCompare("", "created +2w > resolutionDate ")

but I want something like

issueFunction in dateCompare("", "status changed to In Progress +30d > status changed to Done")

How do I do this?
