If you are not an active Snapchat user like me you may get surprised by some features you find in the app even if they were released a long time ago. A Snapchat Map Status feature released in May 2019 is one of the examples.

Many Snapchat features can be considered as secondary (Snapmap or Games for example) compared to the primary feature of capturing and browsing stories.
Snapchat also doesn't tell to users about these secondary features proactively and this makes them some sort of "hidden".
