How reset the Assignee field when you moving a task from one project to another

[Олег]

Hello everyone, please can somebody help me to write a listener in Scriptrunner  that will reset the system field Assignee to unsigned(to default) when you move issue from one project to another?

I would be very grateful if someone suggested a solution or gave advice

I would be very grateful if you could help with writing a script for the listener
