Hi,
VIN next version which is scheduled to be release soon, will allow non admin users to view VIN screens. The only permission they will need is 'read only' on a VM to see it in VIN's screens (map and tables).
Please notice though that this version will only be compatible with NGC 5.5
We are working on the following version to also support NGC 5.1 with that feature.
Thanks,
Moran
