如何将我在KV文件中创建的ScrollView应用于我在Python文件中制作的手风琴

<AccordionItem>:
    size_hint_y: None
    height: '48dp'
    BoxLayout:
        orientation: 'horizontal'
        Label:
            text: root.title
            size_hint_x: 0.8
        Button:
            text: 'Close'
            size_hint_x: 0.2
            on_release: root.collapse()

<Accordion>:
    orientation: 'vertical'
    ScrollView:
        do_scroll_x: False
        do_scroll_y: True
        AccordionItem:
            title: 'Item 1'
            BoxLayout:
                orientation: 'vertical'
                Label:
                    text: 'Content of Item 1'
        AccordionItem:
            title: 'Item 2'
            BoxLayout:
                orientation: 'vertical'
                Label:
                    text: 'Content of Item 2'

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.accordion import Accordion, AccordionItem

class MyAccordion(Accordion):
    pass

class MyApp(App):
    def build(self):
        root = BoxLayout(orientation='vertical')
        accordion = MyAccordion()
        root.add_widget(accordion)
        return root

if __name__ == '__main__':
    MyApp().run()
