App closing in Thunkable X

I have a sort of problem with closing apps and opening apps…
How should I add a exit btn in my app (when button clicks, close app)?
and when I package the apk, the very first screen comes : Made with Thunkable… I just want to ask that will this also come when I publish my app to play store / app store?

Thanks in advance for help…
