Show A Cogwheel When A Repeating Group Is Loading/Refreshing

I’m trying to display something to the user for better user experience when the repeating group is loading or refreshing based on an action taken or a filter applied.

Sometimes it takes 3-5 seconds to refresh.

Any recommendations that others have done to set this up?

Did you ever figure out how to do this?

I know how to implement a splash screen over the entire screen, but I just want a spinner to appear on top of the repeating group element as the rest of the page fine.
