How to add a custom MVC controller to Identityserver3 owin application

问题

I have an owin app which issues OAuth token to different applications. Which is using IdentityServer3 for issuing tokens. My requirement is I need to implement custom MFA for some of the apps before releasing the token. The MFA controller is a custom implementation and have a custom view. I added an MVC controller in my owin app that contains identityserver3 code, and before release the token, to app, I redirected the user to this controller method. My issue is I am not able to read the user session from the MVC controller. Which should an authenticated controller.

So far I tried is created a controller and register it using IdentityServerServiceFactory. I am not sure whether it is possible to inject an external dependency to the IdentityServer3.
