How to use the @opentelemetry/core.NoRecordingSpan function in @opentelemetry/core

if (!parentContext || !isValid(parentContext)) {
      // New root span.
      traceId = randomTraceId();
    } else {
      // New child span.
      traceId = parentContext.traceId;
      traceState = parentContext.traceState;
    }
    const traceFlags = samplingDecision
      ? TraceFlags.SAMPLED
      : TraceFlags.UNSAMPLED;
    const spanContext = { traceId, spanId, traceFlags, traceState };
    const recordEvents = options.isRecording || false;
    if (!recordEvents && !samplingDecision) {
      this.logger.debug('Sampling is off, starting no recording span');
      return new NoRecordingSpan(spanContext);
    }

    const span = new Span(
      this,
      name,
      spanContext,
      options.kind || types.SpanKind.INTERNAL,
      parentContext ? parentContext.spanId : undefined,
      options.links || [],
      options.startTime
    );
    // Set default attributes
    span.setAttributes(
      Object.assign({}, this._defaultAttributes, options.attributes)
    );
    return span;
