Just found that cloudflare worker types has following type for the DispatchNamespace ```export inte

export interface DispatchNamespace {
  /**
   * @param name Name of the Worker script.
   * @param args Arguments to Worker script.
   * @param options Options for Dynamic Dispatch invocation.
   * @returns A Fetcher object that allows you to send requests to the Worker script.
   * @throws If the Worker script does not exist in this dispatch namespace, an error will be thrown.
   */
  get(
    name: string,
    args?: {
      [key: string]: any;
    },
    options?: DynamicDispatchOptions
  ): Fetcher;
}

export interface DispatchNamespace {
  /**
   * @param name Name of the Worker script.
   * @param args Arguments to Worker script.
   * @param options Options for Dynamic Dispatch invocation.
   * @returns A Fetcher object that allows you to send requests to the Worker script.
   * @throws If the Worker script does not exist in this dispatch namespace, an error will be thrown.
   */
  get(
    name: string,
    args?: {
      [key: string]: any;
    },
    options?: DynamicDispatchOptions
  ): Fetcher;
}
