The Samsung apps which come with the Galaxy watch use a rounded on/off slider (on a genlist item) to enable/disable settings.  Where is this component?

I can find an on/off squared checkbox (https://developer.tizen.org/development/guides/native-application/user-interface/efl/ui-components/wearable-ui-components/check) but not the one I see on the Samsung apps.

Is there an example of how to create the rounded on/off?
