80% of the time, people are on cosmos, but aren't really in front of the screen. very similar to how people are used to keeping their ms teams, slack etc online, but not really present. There needs to be a continuous notify sound, or alert or something similar which will keep on pinging the user who we're connected to, until they respond. Because right now, we have to continue saying/shouting/ like 'you there'/'hey'/'can you hear me'/etc to check for the other person to respond.
