Usage of shared experiences

I'm in the process of creating aero experiences and it would be great to track how many users have engaged with the experience. I'll be using the QR code generated to share the content and this will be printed in a physical environment for users to access. I can't seem to find this, am I missing something or is this in development.

If this isn't a feature, can anyone think of a workaround, so I can track the number of engagements with each AR I produce?

thanks
