RevenueCat and watchOS

Has anyone had any luck with RevenueCat and independent watchOS apps? I am having trouble retrieving SKProducts that i setup on app store connect. Is there something different about Watch apps that I need to factor in the configuration of RevenueCat. For example, when it asks for Bundle ID - which bundle ID do i input? My watch app has 3 bundle IDs for the app, the watch app, watchkit extension. There's no documentation out there, it's very confusing.
