当用户点击问题框开始输入时，键盘会出现动画，HStack（包含TextField和Button）会相应地向上移动并显示动画。但是，活动键盘和移动的HStack会覆盖MessageView。如何更改代码，使MessageView也相应地向上移动？
下面是键盘处于非活动状态时的UI：

下面是键盘激活时的UI。键盘涵盖了最新的消息：

    @State var messages: [Message] = [
        Message(text: "Hello!", isMe: false),
        Message(text: "Hi there!", isMe: true),
        Message(text: "How are you?", isMe: false),
        Message(text: "I'm good, thanks. How about you?", isMe: true),
        Message(text: "I'm doing well too, thanks for asking.", isMe: false)
