 When you use the [`join` operator](/azure/data-explorer/kusto/query/joinoperator) instead of union, you need to use a [`hint`](/azure/data-explorer/kusto/query/joinoperator#join-hints) to combine the data in Azure Resource Graph with data in the Log Analytics workspace. Use `Hint.remote={Direction of the Log Analytics Workspace}`. For example:
 
-```kusto
