Replace the example addresses with those of your application. Labels may vary depending on the product version.
Admin console → Applications → Web and mobile apps → Add app → Add custom SAML app.
"Google Identity Provider details" step: download the metadata (Google gives no address) then import it into ID-Kit by pasting the file content.
“Service provider details” step: ACS URL = https://app.example.com/saml/acs ; Entity ID = https://app.example.com/saml/metadata ; Format de l'ID de nom = EMAIL ; ID de nom = Adresse e-mail principale.
Finish, then User access: set the application to "Enabled for everyone" (otherwise: error app_not_enabled_for_user).
