How can I filter the main page of the dashboard by conferenceID?

It is possible to filter conferences for a particular conferenceID (for example, in a URL format), e.g. when a ConfID is used to join a weekly meeting, and to obtain the aggregated metrics within the Service Metrics tab. For a more granular search you can also use the time filters. Specific details of each conference are accessible via the Conference Details tab.
