Dropbox SDK React-Native

Question

I have react-native app for mobile and web. I have Dropbox section that I need to connect with backend. On toggle button I need to show Dropbox button and when I click on button show modal to signIn.

<View style={{ paddingHorizontal: 15 }}>
    <AccordionComponent label="DropBox" type="toggle" content={<></>} />
            <Button
            onPress={onDropboxPress}
            style={styles.dropboxButton}
            textStyle={styles.dropButtonText}
            text={t('DropboxNormal')}
            iconPath={require('@assets/icons/dropbox.png')}
            iconStyle={styles.dropIcon}
            loading={savingIDropUser === ILoadingState.LOADING}
        />
  </View>

I found this
