tracking lost and found in cloud reco

I have my cloud reco project working and want to add some new features. One of the things I would like to do is to be able to turn audio on and off with tracking found and tracking lost for cloud targets similar to how i do it on device builds. Where would i find the documentation to detect tracking lost and found for cloud targets. Help is greatly appreciated.

Thanks

You can find documentation here: https://library.vuforia.com/

Our core samples also demonstrate this functionality.

 

I managed to figure it out and it works great without using the core samples. Thanks.
