In HLC, the optional parameters will use model XXXOptionalParams as the parameter value like here, and the model definition code is

export interface DataProductsCreateOptionalParams
  extends coreClient.OperationOptions {
  /** Delay to wait until next poll, in milliseconds. */
  updateIntervalInMs?: number;
  /** A serialized poller which can be used to resume an existing paused Long-Running-Operation. */
  resumeFrom?: string;
}

but in Modular, it is changed to XXXOptions, like here, and the model definition code is

export interface DataProductsCreateOptions extends OperationOptions {
  /** Delay to wait until next poll, in milliseconds. */
  updateIntervalInMs?: number;
}
