We use Jira cloud. We recently installed ScriptRunner Enhanced Search - Adaptavist
add-on. When I login to Jira, I can see the following sections

I can go to "ScriptRunner Enhanced search" and I can write queries like
issueFunction in linkedIssuesOf("project = xxx") and it works fine.
But when I go to "Issues and filters" section and run the same query, I get
Field 'issueFunction' does not exist or you do not have permission to view it.
How can i integrate this add-on to main jira query search ?
