What are the alternatives to RCTEventEmitter and RCTModernEventEmitter?

I am trying to integrate a Native UI component in react-native using the new architecture with fabric enabled

Here is my spec file

import type {HostComponent, ViewProps} from 'react-native';import type {  DirectEventHandler,  BubblingEventHandler,} from 'react-native/Libraries/Types/CodegenTypes';import codegenNativeComponent from 'react-native/Libraries/Utilities/codegenNativeComponent';type Event = Readonly<{  text?: string;}>;interface NativeProps extends ViewProps {  text: string;  onClickHandler?: DirectEventHandler<Event>; ////Event name should start with on}export default codegenNativeComponent<NativeProps>('MyButtonView',) as HostComponent<NativeProps>;

Then on native side I created following files

public class MyButtonViewManager extends SimpleViewManager<MyButtonView> {    public static final String NAME = "MyButtonView";    ReactApplicationContext mCallerContext;    public MyButtonViewManager(ReactApplicationContext reactContext) {        mCallerContext = reactContext;    }    @NonNull    @Override    public String getName() {        return NAME;    }    @NonNull    @Override    protected MyButtonView createViewInstance(@NonNull ThemedReactContext reactContext) {        return new MyButtonView(reactContext);    }    @ReactProp(name = "text")    public void setQrCodeText(MyButtonView view, String text) {        view.setText(text);    }    @Nullable    @Override    public Map<String, Object> getExportedCustomDirectEventTypeConstants() {        return MapBuilder.of("topOnClickHandler",                MapBuilder.of("registrationName", "onClickHandler")        );    }}public class MyButtonView extends androidx.appcompat.widget.AppCompatButton {    public MyButtonView(Context context) {        super(context);        configureViews();    }    private void configureViews(){        setBackgroundColor(Color.YELLOW);        setOnClickListener(view -> {            ReactContext reactContext = (ReactContext)getContext();            EventDispatcher eventDispatcher = UIManagerHelper.getEventDispatcherForReactTag(                    reactContext ,getId()            );            eventDispatcher.dispatchEvent(new MyButtonClickEvent(getId()));        });    }}public class MyButtonClickEvent extends Event<MyButtonClickEvent> {    public MyButtonClickEvent(int viewId) {        super(viewId);    }    @Override    public String getEventName() {        return "topOnClickHandler";    }    @Override    public void dispatch(RCTEventEmitter rctEventEmitter) {        super.dispatch(rctEventEmitter);        rctEventEmitter.receiveEvent(getViewTag(), getEventName(), Arguments.createMap());    }    @Nullable    @Override    protected WritableMap getEventData() {        WritableMap event = Arguments.createMap();        event.putString("message", "MyMessage");        return event;    }}

What is the alternative to dispatch and RCTEventEmitter as both are deprecated? I was looking into RCTModernEventEmitter and it also extends the deprecated RCTEventEmitter

Also i have to change the event name from OnClickHandler to topOnClickHandler in Native Android side. It was throwing hermes error. Not sure why there should be top prefix, why can't it just be OnClickHandler.
