How to use the @aws-amplify/xr.isVRPresentationActive function in @aws-amplify/xr

await XR.loadScene(sceneName, sceneDomId, sceneOptions);
    } catch (e) {
      const sceneError = {
        displayText: 'Failed to load scene',
        error: e
      }
      logger.error(sceneError.displayText, sceneError.error);
      this.setStateAsync({sceneError});
      return;
    }
    
    XR.start(sceneName);

    this.setStateAsync({ 
      muted: XR.isMuted(sceneName),
      isVRPresentationActive: XR.isVRPresentationActive(sceneName),
      loading: false
    });

    XR.onSceneEvent(sceneName, 'AudioEnabled', () => this.setStateAsync({showEnableAudio: false}));
    XR.onSceneEvent(sceneName, 'AudioDisabled', () => this.setStateAsync({showEnableAudio: true}));
  }

},
    };
    try {
      await XR.loadScene(sceneName, sceneDomId, sceneOptions);

    }

    XR.start(sceneName);

    this.muted = XR.isMuted(sceneName);
