How to use the @azure/core-amqp.Constants.defaultPrefetchCount function in @azure/core-amqp

const linkCreationConfig: RetryConfig = {
        connectionId: this._context.connectionId,
        connectionHost: this._context.config.host,

          retryDelayInMs: 15000
        }
      };

      await retry(linkCreationConfig);

      // if the receiver is in streaming mode we need to add credits again.
      if (this._isStreaming) {
        this._addCredit(Constants.defaultPrefetchCount);
      }
    } catch (err) {
      logger.verbose(
        "[%s] An error occurred while processing onDetached() of Receiver '%s' with address " +
          "'%s': %O",

        this.name,
        this.address,

// close this receiver when user triggers a cancellation.
        this.close().catch(() => {}); // no-op close error handler
      }
      onError(error);
