 * (matching Google's API style guide). They are written explicitly in object
 * literals, so no `Casing` helper runs on the `send()` path; the
 * `protected casing = CasingEnum.CAMEL_CASE` field exists only for the
 * Novu-compatible `sendMessage()` surface.
 *
 * Unlike Slack/MS Teams (plain-text response), Google Chat returns a full JSON
 * `Message` resource on success; `providerMessageId` carries the full resource
 * name `'spaces/<space-id>/messages/<message-id>'`.
