Unable to connect to D365 O&F via add new connection

I am unable to get my D365 for Operations connection setup. I get the following error:

 

Connection test failed: Verify that the associated connection information is valid and that you have access to this OData service. The following exception message was returned from the OData service: One or more errors occurred.

 

I am able to connect to the API via Postman and the one field that doesn't show up in the Scribe connector that I am using to connect is the client_secret parameter.
