My SetState is erasing my previous content

I return this content from my ReviewPictures.tsx screen.

My problem is when i take a new Photo with my Photo Button

My SetState erase the previous Photos List

How to prevent my list to be deleted by my setState ?

The code :

ReviewPictures.tsx ->

  const [content, setContent] = useState<JSX.Element[]>([]);  const navigation = useNavigation<NavigationProp<PhotoshootStackParamList>>();  const Appnavigation = useNavigation<NavigationProp<AppStackParamList>>();  const toRedo = !params?.redo;  useEffect(() => {    setContent(setPageContent());  }, []);  const setPageContent = () => {    const c: JSX.Element[] = [];    picturePaths.forEach((value: string, step: StepAlias) => {      console.log(value);      c.push(<View style={[styles.box, styles.row]}><Text>{I18n.t(`${step}`)}</Text><Image style={styles.image} source={{uri: value}} /><IconButton            icon="camera"            color={Colors.blue500}            size={40}            onPress={() => {              console.log('Pressed');              Appnavigation.navigate('Logged', {                screen: 'Onboarded',                params: {screen: 'Photoshoot', params: {redo: toRedo, onboarded: false, review: step}},              });            }}          /></View>,      );    });    return c;  }; return (<><ScrollView style={styles.container}>{content}</ScrollView><Button onPress={() => navigation.navigate('Mileage')}>Valider</Button></>  );};

Photoshoot.tsx ->

  const [steps, setSteps] = useState<Step[]>([]);  const loadReviewScenario = () => {    if (params?.review) {      setSteps([fromStepAlias(params.review)]);      setIsLoading(false);      // HERE THE SETSTATE SUPRESS THE PREVIOUS CONTENT    }  };

The fromStepAlias coming from Step.ts ->

export const fromStepAlias = (stepAlias: StepAlias): Step => {  console.log(stepAlias.split('_'));  const split = stepAlias.split('_');  return {tyre: split[0] as TyrePosition, whichSideToTake: split[1] as PhotoType};};

What's wrong with my setSteps ?

const loadReviewScenario = () => {    if (params?.review) {      setSteps([fromStepAlias(params.review)]);      setIsLoading(false);      // HERE THE SETSTATE SUPRESS THE PREVIOUS CONTENT    }  };
