Custom SSO with Keycloak and OIDC in Kotlin: Help Needed

Hi everyone,

I'm integrating Appwrite as a BaaS for a mobile application I'm building in Kotlin, and I'm trying to set up custom SSO using Keycloak with the OIDC protocol. I'm facing a few issues and would appreciate some help:

Success Redirect: After hitting sign in, the app is not redirecting back to the application. I assume a deep link redirect URL is missing. How can I properly configure this?

Fetching Username: We need to fetch the username under the scope. Any guidance on how to achieve this would be helpful.

Session Management: We need to store sessions so that users don't have to log in every time they open the app, but I haven't found documentation for this. We also need to implement a sign-out button and fetch the username to display in the app.

OIDC User Details: There is documentation for fetching user details, but it's not working for OIDC. Some identifiers are not recognized by Kotlin. Any solutions or workarounds?

Thanks in advance for your help!
