Javier wants to activate developer mode on his phone, but can't find the right setting. He goes into '''Help > Live Support'''. The phone sends a request to the support app: someone wants support with Settings in es-MX. The application looks in its database of contributors to see who has the appropriate expertise (and language) to help him, and who is online. Among the pool of possible people it selects Maria, and pings her to see if she can provide support. If she doesn't respond then another person is selected from the pool (or maybe many people are asked at once), and if someone else helps Javier then Maria is notified that her help is no longer needed.
Note that Maria would be participating under an alias specific to the support application (though not anonymous), and she will not be fielding support requests all the time (e.g., she may not provide support at work, only after hours).
