How to integrate DokuWiki with Authelia?

[arbdevml]

Hello.
I am trying to integrate DokuWiki with Authelia.

https://www.authelia.com/
Authelia is an open-source authentication and authorization server and portal fulfilling the identity and access management (IAM) role of information security in providing multi-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion for common reverse proxies.

Authelia configuration.yml
Add into the section of "clients"

      - id: dokuwiki
        description: dokuwiki
        secret: '$plaintext$dokuwiki_client_secret'
        public: false
        authorization_policy: one_factor
        redirect_uris:
            - https://dokuwiki.example.com/doku.php
        scopes:
            - openid
            - profile
            - groups
            - email
        userinfo_signing_algorithm: none

Installed on the administration panel "Extension Manager"
