### Summary

Currently, with React Native versions `0.79.x` to `0.80.x`, the
definition of `Fabric View` components has been changed. You can find
that there is no `ViewManager` in the React Native documentation:
https://reactnative.dev/docs/next/fabric-native-components-introduction

Additionaly, `RCTViewManager` could lead to the problem with
registration:

/>
* It could be that the `componentProvider` inside `codegenConfig` fix
the problem


I tested it with different versions of React Native and found that
`ViewManager` is only needed for the old architecture and React Native
versions below `0.74.x`.
