In T220146, we use GuidedTours to show users where they can look for responses after they ask questions from the help panel, mentorship module, and help module. GuidedTour doesn't exist for mobile, and so we need a separate design for that platform.
There may be inspiration in T224883, which uses banners to notify users about their homepage, as a substitute for the desktop version's GuidedTours (T222852).
