Launch app but keep existing one after exit

Is it possible to use the API to have an app launch another app and when the other app is closed it will be go back to the calling app? I’ve developed an app that lists a bunch of streaming apps (like YouTube) but when the user exits YouTube I want the user to be returned to my app.

Currently, no APIs for that feature are provided. If there are any updates, we will let you know via our website. Thank you.
