The handle returned by `https://developer.android.com/reference/kotlin/androidx/compose/runtime/tooling/package-summary#(androidx.compose.runtime.Composition).setObserver(androidx.compose.runtime.tooling.CompositionObserver)` and `https://developer.android.com/reference/kotlin/androidx/compose/runtime/tooling/package-summary#(androidx.compose.runtime.Recomposer).observe(androidx.compose.runtime.tooling.CompositionRegistrationObserver)`. Calling `https://developer.android.com/reference/kotlin/androidx/compose/runtime/tooling/CompositionObserverHandle#dispose()` will prevent further composition observation events from being sent to the registered observer.
