Pull to refresh / Swipe Down to refresh in Apple Watch app in Swift

I want to implement pull to refresh/ swipe down to refresh in my WatchOS project as we see it in native Mail Watch App, I am not able to find any exposed API or Framework for this feature as I didn't get any Apple Documentation or Support for this. Although we have refreshable(action:) for  watchOS 8.0+ in SwiftUI , Kindly if any body can give some reference on how to achieve pull to refresh in Apple Watch app with older OS version in Swift?

for the the refreshable action gets never called in WatchOS, although it is marked as supported on this platform in the documentation (watchOS 8.0+).

As Apple itself offers this feature in mail app, I supposed it is considered as "good" UX so we should be able to use it.
