Thanks for using our plugin.
We have tested the ability to remove the user from the list of users in case of a simple browser closing with our plugin. Allow us to mention that it is possible with the new plugin element - Agora RTC.
Thus, first of all, we recommend you upgrade your plugin to the latest version.
In order to create a required scenario, you need to use the following event:
Also, please note that the user will be removed from the list of participants not immediately. Unfortunately, this process is related not only to the plugin but to the Agora platform and Bubble possibilities.
The user is closing the browser, in few seconds it will be removed from the Agora base, and in a few seconds after it, it will disappear from the Bubble database, and as a result, from the list of online users.
Hope this solution will help you.
