Worked on the preset-io/superset repository to address admin role synchronization issues related to custom OAuth2 configurations. Focused on resolving a bug where the Admin role was not properly synced by re-running the 'superset init' command to refresh permissions, ensuring consistent RBAC behavior. Updated onboarding documentation written in Markdown to clarify the process for assigning the Admin role during new user registration and to guide users in troubleshooting cases where the Admin role exists but is not synchronized. This work emphasized documentation skills and contributed to smoother onboarding and permission management for administrators using the Superset platform.
