In the Azure Bot Service ARM template there is a setting called "isIsolated" which has a vague description says "Whether the bot is in an isolated network".
Is there any documentation available which describes this particular feature and/or an ARM template which shows how we can configure it for a Azure Bot deployment. I believe that there is also an inbuilt Azure Policy related to this feature as well but I am struggling to find any documentation that describes it in more detail.
