When accessing calculator metrics in Webview, why am I getting this message?

"This functionality is not available in APM Webview, please use Workstation,"

So I am not able to see these metrics in Webview. 
All supported APM releases
This is by design due to the additional load that this would add.

For calculator metrics, please use Workstation instead.
