[Question] How can I change the text that is inside a Panel after a certain time or action?

[seradotflac]

class Logs(Widget):
    mouse_over = Reactive(False)

    def render(self) -> Panel:
        return Panel(Align.left("Test", style="white"))

    def on_enter(self) -> None:
        self.mouse_over = True

    def on_leave(self) -> None:
        self.mouse_over = False

class MyApp(App):
    async def on_mount(self) -> None:
        await self.view.dock(Logs(), edge="top", name="right_tab")

Now I want to edit that "Test" later on. How would I do that?
