Hi, I'm working on a project that have actually steamVR version 2.0.1 and unity version 2019.3.13 and I need to upgrade steamVR version to the latest.

We can't see the controller and I tried a lot of things but anything works.
So, could you please help me to solve this problem ?
Thanks in advance.
