JQL issueFunction in linkedIssuesOf does not work

Greetings,

I have tried to apply JIRA CLOUD the following JQL query and it is not working ( when the same solution worked in the On-premise version )

I have Adaptavist ScriptRunner for Jira Cloud" version 1.1.132-AC

project = PRJ1 AND issueFunction in linkedIssuesOf("Project = PRJ2")

Field 'issueFunction' does not exist or you do not have permission to view it.

I need a query to extract  all tickets ( PRJ1) with issue linked to any ticket for PRJ2

could you help me?

Many thanks
