Customer Service Hub load JavaScript on Home Page Grid View (System Views)

I am not able to add custom JavaScript web- resource on Home page Grid View (System Views) if No data is available.

I added JS web-resources in Headers of Grid view.

I observed if no data available, then it does not load scripts. But works fine if data exists.

How this can be achieved ?

Other Solution: I also tried with custom ribbon button but until we don't click button scripts does not load. But I want on load of a view.

Note: Working with Customer Service Hub (Unified Interface)

Please suggest solution.

Thanks in advance.
