I'm getting the following warning even though I'm only using bottomTabs in my project.

To Reproduce

Happens at initial build running react-native run-ios --simulator='iPhone 11' or clicking reload` from the simulator menu

Your Environment

• React Native Navigation version: 6.4.0
• React Native version: 0.63.4
• Platform(s) (iOS, Android, or both?): iOS, but I haven't built in Android so possibly there too
• Device info (Simulator/Device? OS version? Debug/Release?): Simulator, iOS deployment target: 12.0, Debug

Reproducible Demo

I'm not sure how to simply replicate the issue but a Google search for api.topTabs only brings up this page https://github.com/wix/react-native-navigation/blob/master/lib/src/commands/LayoutTreeParser.ts
