What should Mini Program do when he opens the APP (launchApp), and displays the "Open APP" button?

Mini Program has a rigid requirement for opening mobile applications: from mobile apps to Mini Program"s pages, users can open source apps when they visit them.

then I think Mini Program"s page always shows the button "Open APP". What should I do?

currently, Mini Program can open it if he shares it from app.
so, if Mini Program entered directly, I want to jump to a page that downloads APP directly, but Mini Program doesn"t seem to allow users to download it. What should I do with this process?

Jump to the customer service page via < button open-type= "contact" / > , where you can direct users to App Store
