Oauth2 functionality is not in Azure Databricks connector

Hello,

I have requirement to do encrytion/decrytion in databricks to restrict user level permission. In order to work that, I have developed model in DQ and published in PBI service. And configured Oauth2 authentication. 

But, when consumers(users) of the model, while access they are seeing dataset owner access level data. It is not passing users credentials to databricks and fetch data as per role definition.

I knew, this connector is in Public preview. But this is core functionality for any connector in PBI service. Please check and revert ASAP

I really appreciate your early response and Thanks in advance!!
