Trimble Connect app SiteVision questions

Hello, I’m pretty new to Unity and I would like to create something like the system shown below, a QR marker that stores the informations of a model, and after scanned, an overlaying model could be rendered in the specific position.

Here is the link of the demonstration:

I’ve look for the documentations on unity about placing model with ar marker on this website:

https://docs.unity.com/visuallive/en/manual/mob-ar-quick-marker-scan-loading-procedure

But I can’t create a VisualLive account no matter what and I think in order to use the plug-in I’ll have to create a account first? I’m not very sure, I suppose it’s out of service?

I was wondering is there anyway I could use only unity to implement something similar to this? If anyone know any thing that might work I’ll be very happy to know, thankyou.
