For example, we currently have the following, which exposes implementation detail within docs:
https://azuresdkdocs.blob.core.windows.net/$web/cpp/azure-identity/1.5.1/struct_azure_1_1_identity_1_1_client_secret_credential_options.html

We either adjust doxygen knobs to hide that initialization logic in docs, or possibly design our code to not expose such details.
