     * If you are connecting directly to the OpenAI API, use your OpenAI API key in the following way:

     * **Important: use your API key ONLY in a development environment or for testing purposes!**
     * In the production environment, pass your request through a proxy endpoint.
     *
     * If you are using a proxy service to send requests to the OpenAI API, `requestHeaders` can be used to implement authorization for your
     * requests.
     *
     * If the provided value is a function, it should be a function that returns a `Promise` which resolves with the headers object.
     * This way, you can perform an authorization request to your application and receive the authorization token (and also implement
     * any custom logic on the back-end side). The headers object is then used to make the actual call to the AI service.
     *
     * The function is passed {@link module:ai/aiassistant/adapters/aitextadapter~AITextAdapterRequestData#actionId `actionId`}
     * parameter to make it possible to further customize the headers.
