Summary:
This showcases SampleTurboModule usage in RNTester. Notes:
* iOS only for now, and you must use cocoapods version.
* You cannot use Chrome debugger when loading this specific example.
As illustrated in the example, the callsite should access `NativeSampleTurboModule` to access the native side.
