You can filter your audience by these and display listeners with the desired conditions.
To see the most engaged listeners you can easily apply "Min" filters.
For example you can filter people who have joined to your rooms at least 10 times or have listened to you for 8 hours.
Also, if you select a specific room to see its listeners, you'll see these 2 important metrics:
Joined After: You can see if they joined to your room instantly or not.
Stickiness: You can see if they stayed in your room until it ends or just stopped by.
