Return string from lambda expression stream().filter()

Question

I have something like this and I want to get a String as a result

    List<Profile> profile;
    String result = profile
                       .stream()
                       .filter(pro -> pro.getLastName().equals("test"))
                       .flatMap(pro -> pro.getCategory())

getCategory() should return an string but not sure what I have to use to return a string, I tried several things but any worked

Any idea?

Thanks

List<Profile> profile;
String result = profile.stream()
                       .filter(pro -> pro.getLastName().equals("test"))
                       .map(pro -> pro.getCategory())
                       .findFirst()
                       .orElse(null);
