 - **URL-based Configuration**: You can also specify the API endpoint directly in the URL using a query parameter. This is useful for bookmarks or sharing links. For example:

   - `--wait`: Use this with `--rate-limit`. It makes the server wait for the cooldown period to end instead of rejecting the request with an error. This is useful for clients that don't automatically retry on rate limit errors.
 - If you have a GitHub business or enterprise plan account with Copilot, use the `--account-type` flag (e.g., `--account-type business`).
