Storing Logic App Connector api keys in Key vault

Hi,

I am starting to learn deploying playbooks with Microsoft Sentinel. 

Question is on the storage on API keys for Logic Apps connectors. Can these be stored inside an Azure Key Vault - if so how? 

I can use a Logic App to get secrets out of a key vault without issue. I can’t see how to use that secret against the connector. I also can’t see an obvious way from the connector api page in order to do that. 

Cheers,

Michael
