Hi, MY Problem is little different i have create an app and i hosted same app with 3 different URL Like below.

Now my use case is when user visit to example1 website it should use example1-user-pool when visit on example2 it should use example2-user-pool and when user visit on example3 link the app should use example3-user-pool for authentication . How I can achieve above scenario using aws-amplify and @aws-amplify/ui-react library.
