How to handle these on iOS?

Two items im trying to transfer over here that I'm not sure of how to do.

Since app inventor app doesnt run in the background -
Navigating away from the app, but not closing it - then coming back.
Is there a way to capture the "returning to app" scenario?
I pull this off with android via extension currently

additionally, is there a "copy/copy all" function for iOS?
Same deal, I pull it off with an extension on android at the moment
