+     * @param {string | null} opts.projectId
+     * @param {GoogleAuth} opts.googleAuth - Override the default google auth config
+     * @param {AuthClient} opts.authClient - Provide a pre-configured AuthClient instance (alternative to googleAuth)
+     * @param {string | null} [opts.region=process.env['CLOUD_ML_REGION']] - The region to use for the API. Use 'global' for global endpoint. [More details here](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/locations).
+     * @param {string} [opts.baseURL=process.env['ANTHROPIC_VERTEX__BASE_URL'] ?? https://${region}-aiplatform.googleapis.com/v1] - Override the default base URL for the API.
+     * @param {number} [opts.timeout=10 minutes] - The maximum amount of time (in milliseconds) the client will wait for a response before timing out.
+     * @param {MergedRequestInit} [opts.fetchOptions] - Additional `RequestInit` options to be passed to `fetch` calls.
+     * @param {Fetch} [opts.fetch] - Specify a custom `fetch` function implementation.
+     * @param {number} [opts.maxRetries=2] - The maximum number of times the client will retry a request.
+     * @param {HeadersLike} opts.defaultHeaders - Default headers to include with every request to the API.
+     * @param {Record<string, string | undefined>} opts.defaultQuery - Default query parameters to include with every request to the API.
+     * @param {boolean} [opts.dangerouslyAllowBrowser=false] - By default, client-side use of this library is not allowed, as it risks exposing your secret API credentials to attackers.
