ScriptRunner for Confluence - Generate List of Group Permissions for ALL Spaces

I’m trying to find a way to generate a list that will show which spaces contain permissions for a specific user group. I DO NOT want this script to delete or modify any permissions, I just want the list. I looked on the forums and found a few related articles, but nothing seems to be working for me.

This script from the Adaptavist library seems like a good starting point, but I’m a newbie with scripts so I don’t know what needs to be modified to generate a list rather than remove space permissions. Also, I do not know what fields should be updated in the template to run the script (the group I’m looking into is called: WikiAnnouncers)
