Need correct types for a Reducer Manager

[stasguma]

The documentation lacks of example for typescript https://redux.js.org/usage/code-splitting#using-a-reducer-manager so I tried it by myself but couldn`t solve the problem. Need your help.

TypeScript Playground

typescript: 5.3.3 @reduxjs/toolkit: 2.2.1 react-redux: 9.1.0
