Offline support and handle session if user is already login

We have downloaded and created the give application

We have followed the following steps

  1. Login as first user kashee@gmail.com.
  2. Login as second user shankar@gmail.com.
  3. Had some conversation with shankar@gmail.com using chat.
  4. Now exit the app (kill the app).
  5. Now go offline, switch off the network in mobile.
  6. Now opening the app again.
  7. Now again i am able to see login screen.

We need that if user is already login then it should not ask to login again and want to see the conversation had with shankr@gmail.com even if mobile network is off. expecting the data should persist locally in device or realm SDK

in Firebase / AWS Amplify this functionality is working so can you please help to resolve this problem as soon as possible.
