What does a red dot on a Box folder mean?

Excuse me, could you please clarify what the significance of a red DOT on a Box folder is? I've noticed it on a few of my folders and I'm curious about its meaning. Is it an indication of a specific status, such as unread notifications or urgent attention required? Alternatively, could it be related to file sharing permissions or some other aspect of the Box platform? I'd appreciate any insight you could provide.
