Airflow 3 and Oauth Git authentication

[arodrber-ds]

Description
Hello, Today I use airflow on Kubernetes and it's version 2.11.0 and to log into the application I use Git's oauth, below are the configurations:

config:
    webserver:
       authenticate: "True"
       auth_backend: "airflow.contrib.auth.backends.github_enterprise_auth"

webserverConfig: |
    import os
    import requests
    from flask_appbuilder.security.manager import AUTH_OAUTH
    from airflow.www.security import AirflowSecurityManager
    # Configuração OAuth
    AUTH_TYPE = AUTH_OAUTH
    AUTH_USER_REGISTRATION = True
    AUTH_USER_REGISTRATION_ROLE = "Admin" 
    CSRF_ENABLED = True
    # Configurar OAuth com GitHub
    OAUTH_PROVIDERS = [
        {
            "name": "github",
            "icon": "fa-github",
            "token_key": "access_token",
            "remote_app": {
                "client_id": os.environ.get("GITHUB_CLIENT_ID"),
                "client_secret": os.environ.get("GITHUB_CLIENT_SECRET"),
                "api_base_url": "https://api.github.com/",
                "client_kwargs": {
                    "scope": "read:user, read:org",
                },
                "access_token_url": "https://github.com/login/oauth/access_token",
                "authorize_url": "https://github.com/login/oauth/authorize",
                "request_token_url": None,
            },
        }
    ]

However, when I tried to update to Airflow 3, I am unable to perform the same type of action, and the webserver_config.py file is no longer being created in the api-server pod, thus keeping the basic authentication type as below:

What do I need to do to enable this authentication in Airflow 3?
