Codegen and adding listeners

[fgrs]

Description

I'm following this documentation https://reactnative.dev/docs/turbo-native-modules-introduction#1-declare-typed-specification to extend my native module with onError listener. My first issue is when I try to add new function interface in the Spec file

addListener(eventName: string): void // Add an event listener
removeListeners(count: number): void // Remove event listeners

and update kotlin file with

fun removeListeners(count: Int) {
    listenerCount -= count
}

the build fails due to 'count' being an Int.

My second issue is that I don't know how to subscribe to onError using New Architecture and the Spec file instead of importing NativeEventEmitter and NativeModules

I appreciate any help

Steps to reproduce

yarn android

0.76.3

Update: a solution to issue 1 was to change in kotlin: removeListeners(count: Double)
