Hi @maya_fromstein Thank you for reaching out with your question! If you would like to work with the features from your Void analysis, you can share the results as s Web map to ArcGIS Online. This will create a feature layer of your results to use as needed.
With your Void analysis results displayed on the map, just go to the Share results menu and select ArcGIS web map option.
Be sure to enable the option for Export map layers in a new hosted feature service for the most flexibility with the layer.
Once your map is published, you can access the results in ArcGIS Online. Just click the link in the prompt when the publishing completes.
