I am looking for a way to show "comic bubbles" pointing to widgets in Qt6 (QtWidgets/C++)? I would like to show something similar to what is in this picture when a help button is pressed (of course only within the window):

Alternatively: what is a good, Qt-honic way of onboarding a user to an app on the first run?
