    I want to return Observable from GetEmployeeByID function that has a matching productName from allProducts$:

    allProducts$ = this.state$.pipe(
    map(x => x.allProducts as IProducts[] || [] as IProducts[]),
    GetEmployeeByID(Id: number): Observable<IEmployees> {
    return this.allEmployees$.pipe(
    map(res => <IEmployees>res.find(data => data.id === Id) ?? { id: -1, name: "N/A", email: "N/A", gender: "N/A", productid: -1, productName: "N/A" } as IEmployees),
    switchMap((Employee: IEmployees) => {
    return this.allProducts$.subscribe(allProducts => {
    return of({
    productName: allProducts.find(Product => Product.productid == Employee.productid)?.name
    }) as IEmployees
    Code (javascript):
