account/update_profile_image.json and account/update_profile_banner.json are undocumented, right ? It's not even in the list of migrated endpoints : https://docs.x.com/x-api/migrate/x-api-endpoint-map.

I tried the example and have an authentication issue. Credentials I used worked for other endpoints.
