What happens when the user flags the call? Can I as an administrator see the flag in reports? Or is it just information for Genesys?

In Performance > Interactions, Genesys Cloud Supervisors can see that an agent or business user flagged a call as problematic. Flagged is one of several columns that Genesys Cloud supervisors can add to that view. In this view you can see which calls a user flagged as problematic, but any further details are only available to Genesys Cloud engineers.
