Dynamic Content Block - Accessing a jelly variable

[anfield]

Im running a custom script in a dynamic content block which ive adapted from the community here:

https://www.servicenow.com/community/platform-analytics-articles/dashboards-approaches-for-interacti...

Ive added my own code, so that it will return a list of users in the drop down from a certain group. From my second function I am looking to return an object (arrUserList) and pass that to elsewhere in the content block where it is needed - like in the URL above. I'm not familiar enough with how to do that in jelly scripting. Can anyone help? Ive confirmed that the data arrUserList looks correct.

Ive added comments where ive commented out the original code, and added two functions to replace that code (user_lookup and show users)
