Looping through an array of object based on ID in ngrx effects

I want to loop through the ids, present in the array of objects and then pass it to another action. I tried data.foreach and I get an error. Most probably I am not using the correct RXjs operator. Any help in this would be highly appreciated.

Example data= [{id:1, name: 'name1'}, {id:2, name: 'name1'}]

loadSucces$ = createEffect(() =>
            this.actions$.pipe(
                ofType(Actions.loadSuccess),
                switchMap(([data]) =>
// data returns an array of objects, from whose id I want to go through
                    this.service
                        .get('data.id')
                        .pipe(
                            map(serviceData =>
                                Actions.loadDataSuccess({ serviceData })
                            ),
                            catchError(error =>
                                of(Actions.loadDataSuccess({ error }))
                            )
                        )



                )
            )
        );
