 * task tokens issued by service-integration Task states, or pass an
 * `Activity` to scope access.
 * ### Callback Pattern
 * **Example:** Keep a waiting task alive
 * ```typescript
 * const sendTaskHeartbeat = yield* StepFunctions.SendTaskHeartbeat();
 *
 * yield* sendTaskHeartbeat({ taskToken: token });
 * ```
 *
 * @binding
