Dynamic client registration allows to automatically obtain the necessary client credentials (client ID and client secret) from the OIDC provider rather than requiring manual registration. When configured, uses this endpoint to register itself with the OIDC provider during the authentication setup process. This is particularly useful in environments where you want to automate the OIDC client registration process.

If your OIDC provider doesn't support dynamic registration, you would typically register manually in the provider's interface and then configure with the static client credentials.
