SSO for Cognos 11.x and Node JS app over OIDC

We have following requirement: To provide single sign on for Node JS application in IBM Bluemix cloud and Cognos as a service in IBM cloud. The Identity provider is a custom application in Azure supporting OIDC.

Would it be possible to integrate Okta to Identity provider to receive user assertions over OIDC and integrate Okta with Cognos and Node JS application for single sign on of the user?

Authorization would be managed by the respective applications
