Making a persistent SSO with OAuth2 Client and ADFS 3.0

I have a (Ionic) mobile app is registered as an OAuth2 client with ADFS3.0. Now, i am doing Authorization Code Grant Method of OAuth2 as it is the only method supported by ADFS3.0. I am successfully getting the access token, and staying in the session. But, after 1 hour, when the access token expires, and ADFS asks me to enter my credentials again. How to make this a persistent SSO.

I am using Cordova Inappbrowser to call the ADFS Url.
