I created a custom dashboard with custom metric using send custom metric connector in the flow. But I dont see any data points in the graph. I have configured dimensions, facts and enabled monitoring as well.

I am trying to create a custom dashboard using a custom metric. I have included a send custom metric connector and configured dimension which is a string value and facts which is a numeric value. In the dashboard I have switched to advanced mode and chose Panel Type as Application Panel. In the query, I chose From as custom_metric. In the selected Field I specified Facts which is a numeric value and I chose mean() function on it. In the GroupBy Tag, I included Dimension which is a string. I have triggered the flow multiple times and made sure the connector is passed through in execution. I still dont see any data points whatever the time range I selected. Looking for some help on this?
