Running an action only for the client inside a module

So I was trying to make visual effects that only appear on the client done from a module so I can spare one remote event to lower recv. (Module is inside rep storage).

The module mainly runs on the server. Is there a way to just switch it for one function?

I have tried

runService:isClient()

But it always returns false.

How can I change it so that it runs on client for this one function?

Is there a way to do so? If not, how could you work around it?
