How do you configure Logic Apps to log to Log Analytics in an ARM template? - azure

Question

I am trying to deploy a solution with Logic Apps whose log data I would like to go to a Log Analytics workspace. This is easy to configure in the portal via Diagnostic Settings > Add Diagnostic Setting > check 'Send to Log Analytics' and select a pre-existing workspace.
However I can't see from looking at the exported templates for the Logic App, for the workspace, or for the whole resource group, how you configure this link in an ARM template. The documentation doesn't seem to mention this setting at all either.

here's an example to stream to event hub\storage account\log analytics:
