A Webex Messaging App competitor (MS Teams) allows you to go under an individual team, and click on an Analytics tab which displays analytics specific to the Team and all the channels under the team.
Summary: total users, apps, meetings, files
Engagement: posts, replies, mentions, reactions
Graph: Active users, Top inactive channels, meetings, engagement
This is highly requested by members of our org to gauge "Team" engagement.
It will be great if this is incorporated into the Webex Messaging App.
