The Codeless Connector Platform

Can you please provide an example of a properly formatted auth type request when using "grantType": "client_credentials"?  I am trying to connect to another MSFT end point to capture data not currently supported in Sentinel from the ODATA end points on M365 Defender.  However, I can't seem to get the connector to work.  The client_id and client_secret work perfectly from our powershell/function app integrations, but we'd rather move to the easier to maintain CCP.   An example would be polling the "https://api.securitycenter.windows.com/api/software" end point in M365 Defender.  

Here is whatI currently have.  

Thanks!
