Create a new Group named consoleAdmin (case sensitive)
Adding your user to the consoleAdmin group logs you into Minio as an administrator. You can also add groups for the other built in policies, please see Minio Documentation for more details.
Create a new OIDC Client and name it Minio (or whatever you want)
Set Callback URLs: https://minio-console.example.com/oauth_callback
You will need to enter your Client Secret every time you edit the OpenID configuration. It may be best to simply regenerate a new one on Pocket ID and enter that when required instead of managing the secret.
If your are using MINIO_BROWSER_REDIRECT_URL=https://minio.example.com/minio-console/ in your Minio configuration, then use https://minio.example.com/minio-console/oauth_callback for Callback URLs in Pocket ID and Redirect URI in Minio OpenID configuration.
