Like this
Press the button to go to the blue screen and 5 seconds to return to the original screen.
Then, maybe it is a specification, the screen shifts down a little and the button disappears a little. You can press it to press it.
Then, press it again to go to the blue screen, and after 5 seconds, it will return to the original screen.

However, there are many Views. I would like to know the solution here.
