What Is the Real-Time Presence Platform?
The presence status is a key feature to make the real-time platform engaging and interactive for the users (clients).

The presence status is popular on real-time messaging applications and social networking platforms such as LinkedIn, Facebook, and Slack [2]. The presence status represents the availability of the client for communication on a chat application or a social network.
