 * Parameters for the internal polling loop in `enqueueAndGetInference()`.
 *
 * Default behavior:
 * - `initialDelaySec` = 2
 * - `delaySec` = 1.5
 * - `maxRetries` = 80
 *
 * Validation rules:
 * - `initialDelaySec` >= 1
 * - `delaySec` >= 1
 * - `maxRetries` >= 2
 *
 * The `initialTimerOptions` and `recurringTimerOptions` objects let you pass an
 * `AbortSignal` or make the timer `ref`-ed to the `setTimeout()`.
 *
 * @category ClientV2
 * @example
 * ```
 * const pollingOptions = {
 *   initialDelaySec: 4,
 *   delaySec: 2,
 *   maxRetries: 50
 * };
 *
 * const inference = await client.enqueueAndGetInference(
 *   inputDoc, params, pollingOptions
 * );
 * ```
