Does sunroof block UV A and UV B more than 90% in Tiguan?

Hi, everybody.
I just bought a Tiguan SE 2019 AWD with panoramic sunroof.
The darkness of sunroof is good enough to me. But I know that the darkness has nothing to do with UV protection.
I googled the UV protection by windows, and found mixed results. And I couldn't find any specific results for Tiguan 2019.
What I have learned from googling is that sun protection varies by vehicle and even by windows.

1. So I am wondering whether the panoramic sunroof of my car blocks UV A and UV B more than 90%. If not, I will consider tinting on it.
2. What about the wind shield and the front 2 side windows (driver's and passenger's side)? They are not dark at all. But again, the darkness has nothing to do with UV protection.
I am also wondering whether the wind shield and the front 2 side windows protect from UV A and B. If not, I will also consider tinting on them.

Thank you in advance.
