When apps need to ask users to grant permissions through the settings app, it can be difficult for some users to figure out how to do it.
I came across this app: https://play.google.com/store/apps/details?id=com.treydev.pns
See this video showing it: https://youtu.be/eHXBc5Mmsqs
Somehow that app is able to highlight menu items within the settings app to guide the user through the process of granting permissions/adjusting settings, and it does so without asking for the accessibility service or any other permission first.
How can this be accomplished?
