Hi Team,
If you will create a Visualization with
agent.name then It will show that agents only have related data. If data is not available then it will not show that agents.
For Example, I have a dashboard where 3 agents are available but if I apply a filter with a rule ID it will show that agents only have data with a particular rule ID.
Hope this information helps you. Please feel free to reach out to us for any information/issues.
